Abu Bakr narrated to us, he said: Waki’ narrated to us, he said: Sufyan narrated to us, from Layth, from Mujahid, regarding a man to whom two men offered money: one of them is a Muslim brother, and the other has a kinship with the authority. From which of them should he accept? He said: From the one with the kinship.
