The Army of Difficulty

The desert shimmers like hammered bronze under the July sun, and the date palms of Madinah hang heavy with fruit that will never be harvested — not this year, not by the men who planted them. It is Rajab of the ninth year after the Hijrah, and the Prophet Muhammad (peace be upon him) has issued a command unlike any before it: every able-bodied Muslim must march. Not to Badr, a half-day’s ride away. Not to Uhud, visible from the city walls. They must march north — a thousand miles north — through open desert, in the killing heat of high summer, toward a place most of them have never heard of. A small oasis called Tabuk, on the edge of the Roman world.

No one knows exactly what awaits them there. And that, perhaps, is the entire point.

The Army of Difficulty

The Companions called it Jaysh al-‘Usra — the Army of Difficulty — and the name stuck because no other word could contain what they endured. Every previous expedition had been hard, but Tabuk was hard in ways that broke new ground. The distance was staggering: roughly a thousand miles from Madinah to the oasis of Tabuk, a journey of weeks through terrain that offered neither shade nor mercy. The timing was brutal: late July, when temperatures in the Hijaz climb past 110 degrees Fahrenheit and the very air seems to press against the lungs like a hot cloth. And the season was ruinous: August would bring the harvest, the single most important economic event of the year for an agrarian society that lived hand to mouth, season to season.

There were no salaries in seventh-century Arabia. No monthly paychecks, no savings accounts, no safety nets. The harvest was the paycheck — not for the month, but for the year. To march to Tabuk meant abandoning the crops at the moment they ripened, leaving behind the one window of abundance that stood between a family and hunger.

And yet the command was absolute. This was not Badr, which had been voluntary, a raid on a caravan that turned unexpectedly into a battle. Tabuk was fard ‘ayn — an individual obligation on every healthy adult male. The Prophet made no secret of the destination. Unlike every previous expedition, where he employed the classic military tactic of concealing his objective, this time he announced it openly. Everyone knew where they were going, how far it was, and how terrible the journey would be.

“O you who believe, what is the matter with you that when you are told to go forth in the cause of Allah, you cling heavily to the earth? Are you satisfied with the life of this world rather than the Hereafter? But the enjoyment of the life of this world compared to the Hereafter is but little.” — At-Tawbah (9:38)

The Quran’s tone in Surah at-Tawbah is unlike anything found elsewhere in revelation. Nowhere else is the command for struggle issued so bluntly, so repeatedly, so urgently. The surah — also known as Surah al-Qital, the Surah of Fighting — hammers the point with a directness that leaves no room for equivocation:

“If you do not go forth, He will punish you with a painful punishment and will replace you with another people, and you will not harm Him at all.” — At-Tawbah (9:39)

And again:

“Go forth, whether light or heavy, and strive with your wealth and your lives in the cause of Allah.” — At-Tawbah (9:41)

Scholarly Note

The classical scholars differed on the precise military cause of the Tabuk expedition. Ibn ‘Asakir reports a narration that the Jews of Madinah goaded the Prophet into marching north — but this is widely dismissed, since no significant Jewish community remained in Madinah by the ninth year, and Surah al-Isra’ (17:76), which this report cites, is a Makkan revelation with no connection to Tabuk. Al-Hafiz al-Haythami records a narration suggesting the Romans dispatched 40,000 troops southward at the urging of the Ghassanid chieftain, but the chain is weak and the strategic logic questionable — Rome had little reason to send a massive legion into the Arabian interior. A more plausible theory involves the Ghassanid Arabs themselves, a Christian Arab vassal state on the Roman frontier that had previously killed a Muslim envoy and clashed with Muslim forces at Mu’tah. Yet even this does not explain the choice of July, the worst possible month for a desert march. Ibn Kathir and al-Baghawi lean toward a reading of At-Tawbah (9:123) — “Fight those adjacent to you of the disbelievers” — as a divine command to extend Muslim authority northward after consolidating the Arabian Peninsula. Al-Tabari, the earliest major exegete, holds a similar view. The scholarly opinion that emerges most coherently from the sources is that the expedition was primarily a divine test of the believers, commanded by Allah to prepare the Companions for the post-prophetic era of expansion.

The Names of an Expedition

The expedition carries two names in the hadith literature, each illuminating a different facet of the experience.

The first is Ghazwat Tabuk — the Expedition of Tabuk — named after the small oasis that was the army’s destination. The Prophet himself used this name. As Mu’adh ibn Jabal (may Allah be pleased with him) narrates in Sahih Muslim, the Prophet told the army as they drew near: “Tomorrow you shall arrive at the spring of Tabuk. You shall arrive there at the hot time of the day. Make sure you do not touch its water until I get there.”

The second name is Jaysh al-‘Usra — the Army of Difficulty. This was the name the Companions themselves preferred, and Imam al-Bukhari uses both in his chapter heading, writing: “The Expedition of Tabuk, and it is the ‘Usra.” The Quran references this name indirectly:

“Allah has already forgiven the Prophet and the Muhajirin and the Ansar who followed him in the hour of difficulty.” — At-Tawbah (9:117)

Qatadah, the renowned student of Ibn ‘Abbas (may Allah be pleased with them both), confirmed that “the hour of difficulty” (sa’at al-‘usra) refers specifically to the Battle of Tabuk. He described how two or more men would share a single date as their daily ration, passing the pit from mouth to mouth to suck whatever nourishment or comfort they could from it.

Thirty Thousand Souls in the Furnace

The army that assembled was the largest Arabia had ever seen. The books of Seerah report figures as high as 30,000, though this number deserves the kind of healthy skepticism that any honest historian must apply to pre-modern crowd estimates.

Scholarly Note

Ka’b ibn Malik himself, in his famous first-person account preserved in Sahih al-Bukhari, states that the number of participants “could not be listed in any book or register (kitab or diwan).” He offers no specific figure. The estimate of 30,000 appears in later Seerah compilations and may reflect the natural human tendency to inflate numbers for large, sympathetic gatherings — a tendency that scholars like Dr. Yasir Qadhi note is universal and does not constitute dishonesty. If the forces at Hunayn numbered 10,000–12,000 just six months earlier, a tripling of that figure in half a year strains credibility. A more conservative estimate of 15,000–20,000 may be closer to the mark, though the precise number is ultimately unknowable and immaterial to the moral lessons of the expedition.

Whatever the exact count, the logistical challenge was immense. Feeding and watering an army of this size across a thousand miles of summer desert required resources that Madinah simply did not have. The treasury was empty — the Prophet had distributed every last coin of the spoils from Hunayn and Ta’if just six months earlier, keeping nothing for himself or the state. Everything had to be refinanced from scratch.

And so the Prophet stood on the minbar and called for donations. The appeal was direct and devastating in its simplicity: “Whoever finances the Army of Difficulty shall be given Jannah.”

The response became one of the most celebrated episodes of generosity in Islamic history. ‘Uthman ibn ‘Affan (may Allah be pleased with him), whose trade caravan had just returned from the north, donated the entire proceeds — hundreds of camels and thousands of gold coins. The Prophet sat with the pile of gold before him, turning the coins in his hands, and said, as recorded in both Bukhari and Muslim:

“By Allah, whatever ‘Uthman does after today will not harm him.”

‘Uthman himself would invoke this hadith years later, when the neo-Kharijite rebels surrounded his house in Madinah. Ibn ‘Abbas (may Allah be pleased with him) also cited it in his defense: whatever your complaints, the Prophet himself declared that nothing could diminish what ‘Uthman earned that day.

Then came the famous competition between Abu Bakr al-Siddiq and ‘Umar ibn al-Khattab (may Allah be pleased with them both). ‘Umar, hearing the hadith directly from the Prophet, rushed home thinking he could finally outdo his friend. He brought half of his entire wealth — no small sacrifice in a world without paychecks, where the next season’s income was never guaranteed. When Abu Bakr arrived with his contribution, the Prophet asked him: “What did you leave for your family?” Abu Bakr replied: “I left them Allah and His Messenger.” ‘Umar said later: “I will never compete with you again after today.”

The Economics of Sacrifice: Why Tabuk Was Different

To grasp the magnitude of what the Companions gave, we must understand the economic reality of seventh-century Madinah. There were no banks, no insurance policies, no government welfare programs. Wealth was measured in livestock, dates, and grain — all perishable, all seasonal. A man’s two camels were not a luxury; they were his transportation, his livelihood, his emergency fund. Donating them was the equivalent of giving away both your cars, your savings account, and your retirement plan simultaneously, with no guarantee of future income.

The harvest season compounded the sacrifice. Leaving in July meant missing the August harvest — the single largest influx of wealth for the entire year. For farmers, this was not merely an inconvenience; it was an existential risk. A missed harvest could mean a year of hunger for an entire family.

This is why the Quran’s language in Surah at-Tawbah is so forceful. Allah was not merely asking for a military contribution; He was demanding that the believers demonstrate, through material sacrifice, that their attachment to this world was subordinate to their commitment to the divine command. The expedition was, in its economic dimension, a comprehensive test of tawakkul — trust in Allah’s provision.

It is also worth noting that the Prophet’s own methodology was to distribute wealth immediately and completely. He kept nothing in reserve from Hunayn, which meant that Tabuk had to be funded entirely through fresh donations. This was not poor planning; it was a deliberate prophetic practice that ensured the community’s generosity was constantly exercised, never allowed to atrophy through the comfort of surplus.

Yet even with this extraordinary outpouring, the funds ran short. Abu Musa al-Ash’ari (may Allah be pleased with him) narrates that his sub-tribe sent him to the Prophet to request camels for the journey. He arrived at a moment when the Prophet was in an agitated state — most likely due to the machinations of the hypocrites — and was told bluntly: “By Allah, I will not give you anything to ride upon.” Abu Musa returned to his people, devastated, convinced he had somehow caused offense.

But barely any time had passed when Bilal ibn Rabah (may Allah be pleased with him) came running: the Prophet was calling for him. Abu Musa returned to find that fresh funds had arrived, and the Prophet had purchased six camels specifically for his tribe. The incident reveals two things: the Prophet’s meticulous awareness of every unit’s needs, even in the chaos of mobilizing the largest army in Arabian history; and the razor-thin margin on which the entire expedition operated. There was no surplus. Every camel was accounted for, every coin spent the moment it arrived.

The March into the Furnace

They departed after Fajr prayer, passing through Thaniyyat al-Wada’ on the northern edge of Madinah, where the Prophet paused to reorganize the troops. Al-Waqidi records in his Maghazi that he assigned battalions along tribal lines, each with its own leader and flag — a practice that reflected both military pragmatism and the Prophet’s understanding of human nature. Men fight best beside the people they know, the people they trust, the people whose honor is intertwined with their own.

Then the column stretched out into the desert, and the suffering began.

‘Umar ibn al-Khattab was later asked by Ibn ‘Abbas and others to describe what happened. His account is harrowing. The heat was so extreme, the water so scarce, that men believed their throats would collapse from thirst. Search parties sent to find water returned empty-handed, more exhausted than before. In desperation, some Companions slaughtered their own camels to squeeze moisture from the animals’ water sacs — a measure so extreme it meant they would have to walk the remaining distance and the entire journey home.

It was Abu Bakr al-Siddiq who finally broke the silence of endurance: “Ya Rasulallah, make du’a for us.” The Prophet raised his hands, and ‘Umar narrates that he did not lower them before the sky opened and rain poured down, filling every canister and container in the camp.

The miracle is striking not only for its immediacy but for what preceded it. The Prophet had not relied on the supernatural. He had watched his Companions suffer, had suffered alongside them, had allowed the crisis to deepen to its breaking point before divine intervention came. This was the pattern of the entire Seerah — Badr, Uhud, the Trench — the miracle arrives only after the struggle, only after the sacrifice, only after human effort has been exhausted. The lesson, repeated across twenty-three years of prophethood, was unmistakable: take the means, exhaust the means, and only then look to the heavens.

Arrival at the Oasis

When the army finally reached Tabuk, they found not a lush spring but a thin sliver of water — “like the strap of a sandal,” as Mu’adh ibn Jabal describes it in Sahih Muslim. The oasis had nearly dried up in the summer heat. Two men had arrived ahead of the main force and, despite the Prophet’s explicit instruction, had touched the water. The Prophet rebuked them sharply — Mu’adh, out of respect, declines to quote the exact words, saying only: “He said what Allah wanted him to say.” It is a small but luminous example of the Companions’ adab — their instinct to protect the Prophet’s dignity even in the act of honest narration.

Then the Prophet washed his hands and face in the remaining water, and it began to gush forth until the entire army — thousands upon thousands of men — drank their fill. And standing at that small oasis in the middle of nowhere, the Prophet turned to Mu’adh and said, as recorded in Sahih Muslim:

“O Mu’adh, if you live long enough, you will see this very land become a land of greenery and gardens.”

At the time, the statement must have seemed almost fantastical. Tabuk was a forgotten point on the trade route between Syria and Yemen, a place where no one lived, where no civilization had taken root. Today, Tabuk is one of the largest cities in northern Saudi Arabia, with a population exceeding half a million, known for its agriculture, its greenery, and its gardens — exactly as the Prophet described it fourteen centuries ago.

The army camped at Tabuk for approximately twenty days. The Prophet prayed qasr — the shortened traveler’s prayer — throughout the entire stay, a detail that would later fuel centuries of juristic debate about the permissible duration of shortened prayers during travel.

Scholarly Note

The Prophet’s practice of praying qasr for twenty days at Tabuk became a major point of contention in Islamic jurisprudence. All four Sunni schools of law — Hanafi, Shafi’i, Maliki, and Hanbali — agree that this narration applies specifically to a state of military uncertainty, where one does not know when the enemy might attack or when one might depart. They hold it cannot be extrapolated to ordinary travel where the duration of stay is known in advance. Other scholars, however, have used this narration more broadly. The debate remains active in Islamic legal discourse.

A Battle Without a Battle

No Roman legions materialized. No Ghassanid cavalry charged from the north. The great confrontation that the entire expedition had been built around simply never happened. And yet the absence of battle did not make the expedition a failure — far from it.

Khalid ibn al-Walid (may Allah be pleased with him) was dispatched with several hundred riders to Dawmat al-Jandal, where he captured Ukaydir, the Christian king of the Kindah tribe, in circumstances so improbable they bordered on the miraculous. The Prophet had told Khalid he would find the king away from his army, among his cattle. And so it happened: Ukaydir’s own herd of cows had battered against his palace door all night, driving him out before dawn with only a handful of servants. Khalid’s force found him in the open, defenseless. Ukaydir agreed to pay the jizya and sever his ties with Rome.

One by one, the northern Arab tribes followed suit. Peace treaties were signed, alliances forged, the Roman frontier sealed. The political achievement was enormous: the entire northern border of the nascent Muslim state was secured without a single sword being drawn. The path was cleared for what would come after the Prophet’s death — the great futuh, the opening of Syria, Iraq, Egypt, and Persia under the Rightly Guided Caliphs.

And perhaps this was the wisdom all along. The expedition was never about a battle. It was about preparation — the forging of an army, a community, a generation capable of carrying Islam beyond Arabia after the Prophet was gone. Tabuk was the final ghazwa, the last military expedition the Prophet would ever lead. After this, there would be the Farewell Hajj, the final illness, and then the Companions would be on their own. They needed to know they could endure the impossible. They needed to know it in their bones, in their blistered feet, in their parched throats, in the memory of a date pit passed from mouth to mouth under a merciless sun.

The Hypocrites and the Honest

But the expedition revealed more than courage. It also exposed the fault lines within the Muslim community with ruthless clarity. The hypocrites — the munafiqun — had been a persistent undercurrent in Madinah since the earliest days after the Hijrah. Tabuk brought them into the open.

Some fabricated excuses to avoid the march. Others went reluctantly, sowing discord along the way. The Quran captures their psychology with surgical precision:

“Had it been an easy gain and a moderate trip, they would have followed you, but the distance was long for them.” — At-Tawbah (9:42)

When the Prophet returned to Madinah, he prayed two rak’at in the mosque — a neglected sunnah of homecoming — and then sat to receive the stragglers. Approximately eighty men lined up to offer their excuses. The Prophet accepted each one, asked Allah’s forgiveness for them, and left their inner truth to Allah. It was his nature: gentle, trusting, willing to take people at their word even when the words rang hollow.

For this, Allah gently corrected him:

“Allah has pardoned you — why did you give them permission before it became clear to you which of them were truthful and which were liars?” — At-Tawbah (9:43)

The verse is remarkable for its structure: the pardon comes before the reproach, a divine tenderness that the scholars have noted across multiple instances of prophetic ijtihad — the Prophet’s exercise of his own judgment in matters where no specific revelation had yet been given.

But three men did not lie. Three men — Ka’b ibn Malik, Murarah ibn Umayya, and Hilal (may Allah be pleased with them all) — stood before the Prophet and confessed the unvarnished truth: they had no excuse. They were healthy. They were wealthy. They simply had not gone.

Ka’b ibn Malik’s account of that moment, preserved in Sahih al-Bukhari, is one of the most psychologically penetrating narratives in all of hadith literature. When his turn came, the Prophet smiled at him — but it was, Ka’b says, “the smile of an angry man.” Not the full, warm smile of welcome. Something tighter, something strained. The Prophet knew Ka’b’s record. He knew about the two camels, the good health, the participation in every previous battle. And he was disappointed.

“What is your excuse, O Ka’b? Did you not purchase a camel?”

Ka’b’s response is a masterclass in the theology of honesty: “By Allah, O Messenger of Allah, if I were sitting before any other person in this world, I could have talked my way out of his anger — I have been given the gift of eloquent speech. But if I were to tell you a lie today to please you, Allah would expose me and make you angry at me tomorrow. And if I tell you the truth, even though you may be angry at me today, I can hope that Allah will forgive me. Ya Rasulallah, I have no excuse.”

The Prophet said: “As for this man, he has spoken the truth. Stand up, and Allah will decide your fate.”

What followed was a fifty-day social boycott — a punishment so total, so all-encompassing, that Ka’b described his own city as feeling like a foreign land. But that story, with all its anguish and its luminous resolution, belongs to the next chapter.

The Last March

The army returned to Madinah, and the Prophet never led another military expedition. Tabuk was the end of the ghazawat — the final chapter in a military career that had begun with the small, uncertain raid at al-Abwa in the second year of Hijrah. From seventy men at Badr to thousands at Tabuk, the arc of those seven years traced the transformation of a persecuted community into a civilization.

But the real victory of Tabuk was not territorial. It was spiritual. The Companions who marched through that furnace — who gave up their harvests, slaughtered their camels, shared single dates between two or three men — emerged from the ordeal as something more than they had been before. They had proven, to themselves and to history, that their faith could withstand any test. They had been weighed in the scales of ‘usra, of difficulty, and they had not been found wanting.

The Quran would record their triumph with a tenderness that matches the severity of the trial:

“Allah has already forgiven the Prophet and the Muhajirin and the Ansar who followed him in the hour of difficulty, after the hearts of a group of them had nearly deviated, and then He forgave them. Indeed, He was to them Kind and Merciful.” — At-Tawbah (9:117)

In the shadow of that forgiveness, three men still waited — Ka’b, Murarah, and Hilal — walking through empty streets where no one would meet their eyes, praying in a mosque where no one would return their greetings, learning in the hardest possible way that honesty, even when it costs everything, is the only currency that holds its value before Allah. Their story — the boycott, the anguish, the letter from the Ghassanid king, and the dawn when revelation finally broke their chains — awaits us next.
