He therefore emigrated to Medina and settled there, and he was given permission to fight after having previously been forbidden to do so before the Hijrah, for an evident wisdom. He recited, “Permission [to fight] has been granted to those who are being fought because they were wronged, and Allah is surely able to help them” (22:39). From then on he began dispatching military detachments.

In the second year, Allah made zakat and fasting obligatory upon His servants. The verses concerning fasting and zakat were revealed in that very year when they were prescribed. As for His words, “And woe to the idolaters (6) who do not give zakah” (41:6–7), what is meant here is the zakah of the heart—its purification through monotheism and the abandonment of idolatry.

That same second year also witnessed the Battle of Badr. The cause was a Quraysh caravan laden with tremendous trade goods from Syria; the Prophet ﷺ set out with a light column of his Companions to seize it. Quraysh marched out to protect the caravan, and the two forces converged at Badr without prior arrangement. The caravan escaped, while the main body met the Messenger and his Companions. The polytheists numbered a full one thousand men with horses, whereas the Muslims were three hundred and a few more, sharing only seventy camels and riding them by turns.
Allah routed the idolaters with a crushing defeat: their chiefs and nobles were slain, many were taken captive, and a calamity befell them the like of which they had never experienced. Concerning this battle and its details Allah revealed Surah al-Anfal.
After the Prophet ﷺ returned to Medina triumphant, those of the Aws and Khazraj who had not yet embraced Islam were humbled, and some of them entered the faith hypocritically. For that reason, all the verses dealing with the hypocrites were revealed only after the Battle of Badr.
- Then, in the third year, came the Battle of Uhud: the idolaters advanced and mustered their forces against the Muslims until they reached the outskirts of Medina. The Messenger of Allah ﷺ went out with his Companions, arrayed and organized them, and they met at Uhud, the well-known mountain to the north of Medina.
