The Madinan Period: Brotherhood, Constitution, and Early Battles

The arrival in Madinah required the Prophet, peace be upon him, to build a community from nothing — a community composed of people from different tribes, different cities, and different prior loyalties. He addressed this with two foundational acts: the Brotherhood and the Constitution.

The Brotherhood — al-Mu'akhat — paired each Muhajir, one of the emigrants from Mecca, with an Ansar, one of the helpers of Madinah. These were not ceremonial partnerships. Abd al-Rahman ibn Awf arrived in Madinah with nothing. His Ansari brother, Sa'd ibn al-Rabi', offered to divide everything he owned in half and, if Abd al-Rahman wished, to divorce one of his wives so he could marry her. Abd al-Rahman, moved by the generosity, asked only to be shown the marketplace and within a short time had established himself independently through trade. The depth of this bond meant that in the earliest period, Ansar even inherited from their Muhajir brothers — a practice later abrogated when the normal rules of inheritance were established.

The Constitution of Madinah — referred to in the seerah as the Sahifah — was a written document establishing the terms of coexistence between the Muslim community and the various Jewish tribes and Arab clans of Madinah. It recognized them as a single ummah in matters of external defense, while preserving their internal affairs and religious practices. It established that the Prophet would be the final authority in disputes. Historians regard this as one of the earliest written political constitutions in history.

The conflicts that defined the Madinan period began with smaller skirmishes and expeditions before escalating into major battles. The Battle of Badr in the second year of the Hijra was the decisive first confrontation. A Muslim force of approximately 313 men met a Quraysh army of nearly 1,000. The victory at Badr was total: seventy Quraysh were killed, including Abu Jahl, and seventy were taken prisoner. The Quran described it as a day when angels fought alongside the believers. In the seerah, the Prophet weeps over Abu Jahl's body not from grief but from the weight of what has passed — a man who had heard the truth and hardened against it.

The Battle of Uhud in the third year was a harder lesson. The Muslim archers stationed on the hill of Uhud were ordered not to leave their position regardless of what happened. When it appeared the battle was won, many descended to collect spoils. The Quraysh cavalry commander Khalid ibn al-Walid — not yet a Muslim — saw the opening and swept around the hill. The Muslim lines broke. Seventy were martyred, including Hamzah ibn Abd al-Muttalib. The Prophet himself was wounded. The Quran's response to Uhud was not rebuke alone but profound pastoral care, addressing the grief and confusion of the Companions with explanation and consolation.

The Battle of the Trench — al-Khandaq — in the fifth year saw the Muslims face a confederation of ten thousand from Quraysh, their allies, and the Banu Nadir. On the suggestion of Salman al-Farisi, the Muslims dug a trench around the exposed northern approach to Madinah. The siege lasted weeks. It was broken not by sword but by the cold, internal divisions among the Confederates, and the intervention of Nu'aym ibn Mas'ud, who sowed distrust between the various factions. Allah sent a bitter wind that scattered the encampment and the confederation dissolved, marking the last time Quraysh would take the military offensive.
