Musannaf Ibn Abi Shaybah

Hazrat Rifa’ah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) gathered the Quraysh and said: “Is there any outsider among you?” The people replied: “No, except for our nephews, our slaves, and our allies.” The Prophet (peace and blessings be upon him) said: “Your nephews are from among you, your allies are from among you, and your slaves are from among you. Indeed, the Quraysh are truthful and trustworthy. Whoever seeks out their faults and mistakes, Allah will cause him to fall on his face.”
