Sayyiduna Abu Juhayfah (may Allah be pleased with him) said: I and two men from Banu Amir came into the presence of the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Where are you from?" We said: From Banu Amir. He (peace and blessings be upon him) said: "You two are from me."
