The first Friday prayer at Banu Salim

According to al-Mas'udi this was the first Friday prayer ever held in Islam. The Prophet set out from Quba on a Friday, with the Helpers clinging to the reins of his she-camel, and he said: "Leave her alone, for she is commanded." Then the time of prayer overtook him in the Banu Salim, and he prayed with them. ²

It happened in the bottom of the valley known as the valley of Ranunaa. ²

Al-Mas'udi says the jurists disputed the number by which the Friday prayer is complete. Al-Shafi'i and those with him held that it is not obligatory until there are forty or more, and others among the jurists of Kufa disagreed with him. ²

Other sources report the first Friday before the Hijra; see the first Friday prayer in Yathrib. Comparing the two accounts needs an additional source.
