The Treaty of Medina

The ink has barely dried on the walls of the new mosque. The mudbrick is still settling, the palm-trunk pillars still fragrant with sap. Medina — or Yathrib, as its inhabitants still instinctively call it — is a city of overlapping loyalties, simmering rivalries, and cautious hope. Arabs and Jews, farmers and merchants, idol-worshippers and monotheists share the same wells, haggle in the same markets, and eye one another across the same dusty lanes. Into this volatile mosaic steps a man who arrived weeks ago as a refugee and is now, by the sheer force of moral authority, becoming something no one in Arabia has ever quite seen before: a leader whose power rests not on blood or wealth, but on an idea.

And the idea needs a framework. It needs to be written down.

A Constitution Before Constitutions

Sometime in the earliest weeks after the Hijrah — before the call to battle, before the change of the Qibla, before the hypocrites even had a name — the Prophet Muhammad (peace be upon him) dictated a document that would define the political, legal, and social architecture of the world’s first Islamic polity. Modern scholars call it the Treaty of Medina, the Constitution of Medina, or simply al-Sahifah — “the Document.” It is, by any measure, one of the most remarkable political texts of the ancient world.

The treaty was not born from crisis. No siege prompted it, no assassination attempt catalyzed it. It appears to have emerged from pure foresight — the recognition that a city of competing tribes, faiths, and grudges could not be governed by custom alone. It needed a covenant, explicit and binding, that would spell out who owed what to whom, and what would happen when things went wrong.

Scholarly Note

The full text of the treaty is preserved primarily in Ibn Ishaq’s Sirah, where he introduces it with the phrase “it has been narrated to me” without providing a complete chain of narrators (isnad) back to the Prophet ﷺ. This absence of a full isnad has led some scholars to question its authenticity. However, Musnad Imam Ahmad records a phrase from the treaty with a chain, confirming at least partial attestation. Many modern researchers, including Muhammad Hamidullah in his landmark study The First Written Constitution in the World (1941), argue that the archaic language of the document — vocabulary and syntax that were already unusual by Ibn Ishaq’s time — strongly suggests authenticity. A forger writing 150 years after the Prophet would not have composed in such difficult, pre-classical Arabic. The majority of contemporary scholars accept the treaty as genuine.

The document itself is not organized the way a modern legal mind would expect. There are no numbered articles, no clean separation of topics. Sentences tumble after one another — clause upon clause, tribe name after tribe name — in a style that mirrors the oral culture from which it emerged. To read it in the original Arabic is to encounter a world where governance was still finding its written voice. And yet within this seemingly chaotic text lies a structure of breathtaking sophistication.

One Ummah: The Muslim Clauses

The treaty opens with a declaration that would have been incomprehensible to any Arab a generation earlier:

The believers from the Quraysh and from Yathrib, and those who join them, are one Ummah to the exclusion of the rest of mankind.

One Ummah. Not one tribe, not one clan — one Ummah. The word itself carries extraordinary weight. It derives from umm, “mother,” which in turn traces back to the root amma — “to aim for, to intend.” An Ummah, then, is a community of shared purpose, a people so bound together they might as well share a single mother. It is the word Allah uses in the Quran:

“Indeed this, your Ummah, is one Ummah.” — Al-Anbiya (21:92)

Notice what the treaty does not say. It does not say “the Banu Hashim and those who follow them.” It does not define belonging by lineage. It says the believers — from Quraysh (the Muhajirun) and from Yathrib (the Ansar) — are one body. Bilal ibn Rabah (may Allah be pleased with him), the Abyssinian former slave, and Abu Bakr al-Siddiq (may Allah be pleased with him), scion of one of Mecca’s noblest families, stand on identical legal footing. In a world where your father’s name was your passport, your credit score, and your life insurance, this was a revolution written in ink.

The treaty then names over forty sub-tribes — the Banu Awf, the Banu Harith, the Banu Sa’idah, and dozens more — specifying that each would retain responsibility for its own internal affairs: blood money disputes, ransoming of prisoners, and care of the poor. The welfare system was local, not national. If a member of the Banu Awf fell into poverty, the Banu Awf would take care of him. If someone owed blood money — a staggering sum, equivalent to one hundred camels — the tribe would collectively shoulder the burden.

Blood Money and Collective Responsibility in Islamic Law

The concept of diyah (blood money) was not invented by Islam but was radically reformed by it. In pre-Islamic Arabia, blood feuds could spiral across generations, with entire clans locked in cycles of retaliatory killing. The Sharia replaced vendetta with a precise financial mechanism: in cases of accidental manslaughter, the perpetrator owed a fixed amount (traditionally 100 camels for a male victim) and was required to fast two consecutive months. Crucially, Islamic jurisprudence stipulated that the tribe (aqilah) would help bear the financial cost — not as punishment, but as communal solidarity. The perpetrator would pay the largest share according to their means, with the remainder distributed across the community. This principle, enshrined in the Treaty of Medina at the tribal level, represents one of the earliest forms of collective social insurance in recorded legal history. The treaty’s insistence that each sub-tribe manage its own blood money disputes was both practical — centralizing such claims would have been administratively impossible — and philosophically consistent with the federalist structure the Prophet was building.

But the treaty’s most striking Muslim clause may be its simplest. It declares that all Muslims shall unite against anyone who commits injustice — even if the wrongdoer is one of their own. This echoes the Hilf al-Fudul, that pre-Islamic pact of justice the young Muhammad had joined decades earlier in Mecca, where the noblest men of the city swore to defend the oppressed regardless of tribal affiliation. Now, in Medina, the same principle is elevated from tribal honor code to constitutional law.

And there is the matter of dhimmah — protection. The treaty declares that the protection granted by any Muslim is binding on all Muslims. Even the humblest believer — even, according to the majority of scholars, a discerning child or a slave — could grant safe passage to an outsider, and that guarantee would be honored by the entire community. In a world of rigid hierarchy, this was a radical leveling: when it came to the sacred act of granting protection, the slave’s word carried the same weight as the chieftain’s.

An Ummah Alongside an Ummah: The Jewish Clauses

The treaty’s provisions for the Jewish tribes of Medina are perhaps its most discussed — and most misunderstood — section. The document names the Jewish clans individually: the Jews of the Banu Awf, the Banu Amr, the Banu Harith, and roughly a dozen others. These were not merely the three major tribes (Banu Qaynuqa, Banu Nadir, Banu Qurayzah) that dominate later narratives, but a constellation of smaller communities woven into the fabric of Medinan life.

The treaty’s language regarding them is striking in its generosity:

The Jews are one Ummah alongside the believers (ummatan ma’al mu’mineen).

One Ummah alongside the believers. Not subordinate, not marginal — alongside. They are granted the same structural autonomy as the Muslims: their own internal courts, their own responsibility for blood money and social welfare, their own religious life. The Prophet is explicitly declining to interfere in Jewish internal affairs. Two Jews in a commercial dispute, a case of theft within the community, even a murder between members of the same tribe — all of this falls under Jewish jurisdiction. Only when a dispute crosses communal lines, involving both Muslims and Jews, does it rise to the Prophet’s court.

The obligations, too, are symmetrical. Just as the Muslims must care for their own poor, so must the Jews. Just as the Muslims must contribute to the common defense, so must the Jews. If an external enemy attacks Medina, both communities will share the financial burden of defense. The city’s security is a shared project, and neither community can free-ride on the other’s sacrifice.

There are, however, conditions that reflect the political realities of the moment. No Jew may leave Medina — that is, renounce citizenship and join another polity — without informing the Prophet. This is not a restriction on travel but on allegiance: in a world where geography was loyalty, quietly relocating to another tribal territory was tantamount to defection. The modern equivalent would be the formal process of renouncing citizenship — a requirement that exists in virtually every nation-state today.

And there is a protective clause: any Jew who wishes to embrace Islam shall be helped and protected, and no injustice shall be done to him. Conversion is a right, and the convert’s safety is guaranteed by the state.

Scholarly Note

The treaty’s provisions regarding the Jewish tribes have been interpreted in sharply divergent ways. Some Western scholars have read the document as evidence of an anti-Semitic design, arguing that the Prophet was deliberately isolating the Jewish communities for future expulsion. This reading is contradicted by the treaty’s own language, which grants the Jews a status of remarkable equality — “one Ummah alongside the believers” — and imposes identical obligations on both communities. From the Islamic perspective, the subsequent conflicts with the Banu Qaynuqa, Banu Nadir, and Banu Qurayzah resulted not from the treaty’s design but from those tribes’ violations of its terms. On the other extreme, some Muslim writers have overstated the treaty’s significance, with one prominent North American Muslim academic in the 1980s claiming it was the direct basis for the American Constitution — a claim that, while well-intentioned, lacks historical evidence and, as Yasir Qadhi notes, risks making Muslims “laughingstocks” in academic circles. The truth, as is often the case, lies between the extremes: the treaty was genuinely novel for its time, and certain of its concepts were eventually transmitted — through many intermediaries — to later political traditions, but direct influence on any specific modern constitution cannot be demonstrated.

The Pagans: A Surprising Inclusion

Perhaps the most overlooked section of the treaty concerns the mushrikun — the idol-worshippers who still lived in Medina. Their presence is itself a revelation: even after the Hijrah, even with the mosque built and the Ummah declared, there were still pagans walking the streets of the Prophet’s city. They would not convert en masse until after the Battle of Badr, when the stunning Muslim victory made the political calculus unmistakable.

The treaty does not demand their conversion. It does not threaten them. It does not even marginalize them. What it does is draw a single, clear line: no pagan in Medina may offer protection to the Quraysh or in any way intervene in the conflict between Mecca and the Muslim community. Your heart is your own, the treaty effectively says. But your hands must stay out of this fight.

This clause reveals something profound about the Prophet’s political philosophy in this early period. He was not building a theocratic state that demanded uniformity of belief. He was building a polity — a community of communities — that demanded loyalty to a shared civic order. You could worship your idols in your home. You could not use your home as a staging ground for Mecca’s interests.

The permissibility of pagans residing in the Islamic state became a matter of jurisprudential debate in later centuries. The Hanafi school, drawing partly on this very precedent, held that the right of residence in Dar al-Islam extended to idol-worshippers as well as to the People of the Book — a position that would have significant implications for the Mughal Empire’s governance of Hindu-majority populations centuries later.

Sacred Ground, Shared Law

The treaty’s final sections apply to everyone — Muslim, Jew, and pagan alike. They establish Medina as a haram, a sacred precinct, within defined boundaries: the mountains of Ayr and Thawr to the south and north, and the two volcanic plains (harratain) to the east and west. Within this zone, no weapons may be brandished, no trees uprooted, no game hunted. The sanctity that Mecca had claimed for centuries by virtue of the Ka’bah, Medina now claims by prophetic decree.

And then the treaty’s most consequential general clause: any disagreement between the peoples of this covenant that threatens internal discord (fasad) shall be referred to Allah and His Messenger. This is the moment the Prophet’s authority becomes constitutional. He is no longer merely a spiritual guide whom people choose to consult. He is the final court of appeal for every community in the city — the arbiter whose rulings carry the force of law.

The treaty closes with a warning and a promise. The warning: whoever betrays this covenant, whoever aids a rebel against its terms, will bear the curse of Allah, the angels, and all of mankind, and no good deed will be accepted from him. The promise: whoever leaves Medina peacefully shall be safe, and whoever enters peacefully shall be safe, unless they have committed a crime.

And Allah will protect those who are pious and righteous, and Muhammad is His Messenger.

With those words, the treaty ends. And with those words, something unprecedented in Arabian history begins.

The Architecture of a New World

Step back and consider what has happened. A man who arrived in Medina as a refugee — without an army, without a treasury, without a single acre of land to his name — has, within weeks, established a political order that grants religious minorities autonomous legal status, defines mutual defense obligations between communities of different faiths, creates a sacred civic space with enforceable rules, and positions himself as the supreme judicial authority of a multi-ethnic, multi-religious city-state.

Some modern scholars have described this as a “federalist” system — semi-independent communities united under a shared security umbrella and a common court of last resort. The comparison is imperfect, as all modern analogies must be, but it captures something real. The Prophet was not micromanaging the internal affairs of every tribe and clan. He was establishing the minimum conditions for coexistence: shared defense, shared justice, shared sacred space. Everything else — your poor, your disputes, your customs — was yours to manage.

This principle would later be formalized in Islamic jurisprudence as one of the five great maxims of fiqh: al-urfu muhakkam — in the absence of a specific Sharia ruling, the established customs of a people are given legal weight. The Treaty of Medina is, in many ways, the first practical application of this principle: the Prophet accepted the legal norms and social structures of each community, intervening only where those norms conflicted with the overarching covenant.

And consider the treaty’s implicit testimony about religious freedom. The Jews practice their faith unmolested. The pagans worship their idols without coercion. The only restrictions are civic, not theological: don’t betray the city, don’t side with its enemies, don’t leave without notice. John Locke, writing his Letter Concerning Toleration in 1689 — more than a thousand years later — would hold up the Ottoman Empire as a model of religious coexistence to shame his fellow Christians, who were still killing one another over doctrinal differences. The seeds of that Ottoman tolerance were planted here, in a mudbrick city in the Hijaz, by a man the world would later accuse of intolerance.

The First Islamic State

Look back at the sequence of events since the Prophet’s arrival. First, he built a mosque — the spiritual foundation, the reminder of purpose. Then he established the Mu’akha, the brotherhood between Muhajirun and Ansar — the social foundation, the bonds of solidarity that would hold the community together through the trials ahead. And now, with this treaty, he has laid the political foundation — the constitutional framework that defines rights, obligations, and the rule of law.

Mosque. Brotherhood. Constitution. In that order. It is a sequence worth contemplating: worship before solidarity, solidarity before governance. The Prophet did not begin by seizing power or declaring a state. He began by reminding people why they existed. He built community before he built institutions. And when the institutions came, they were designed not to concentrate power but to distribute responsibility — tribe by tribe, community by community — while reserving for divine guidance the ultimate authority to resolve what human custom could not.

The treaty would be tested. Within months, the Battle of Badr would transform the political landscape of Arabia. Within years, each of the three major Jewish tribes would, from the Muslim perspective, violate the covenant’s terms — and face the consequences the treaty itself prescribed. The pagans of Medina would vanish as a distinct group, absorbed into Islam after Badr made neutrality untenable. And the Prophet’s authority, here established by consensus and covenant, would be confirmed again and again by revelation and by victory.

But all of that lies ahead. For now, in these first fragile weeks, the treaty stands as a monument to what is possible when power is exercised with restraint, when diversity is governed by covenant rather than coercion, and when a refugee builds not a fortress but a framework.

The next chapter of the Medinan story will turn the community’s gaze from the ground beneath their feet to the sky above their heads — and to a question that had been quietly burning in the Prophet’s heart. Every day, the Muslims of Medina lined up for prayer facing Jerusalem, the qibla they shared with the People of the Book. But a change was coming — a change that would define the Ummah’s identity, break with the past, and force every soul in the city to choose where they truly stood.
