 During Muhammad's activities in Mecca and Medina, the Sulaym, as their Qurayshi allies, were hostile to Muhammad and his message.An exception among the tribesmen was Safwan ibn Mu'attal, a member of the Dhakwan in Medina who became a companion of Muhammad.Several clans of the Sulaym joined the Kilabi chief Amir ibn al-Tufayl in his attack targeting Muslim missionaries at Bi'r Ma'una in 625.
