Sayyiduna Abdul Rahman bin Awf (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Quraysh, the Ansar, Juhaynah, Muzaynah, Aslam, Ghifar, Ashja' and Sulaym (that is, the people of these tribes) are my companions; they have no protector (wali) besides Allah Almighty and His Messenger (peace and blessings be upon him)."
Al-Tabarani recorded it, and Abu Ya'la and al-Bazzar recorded something similar. The narrators of al-Bazzar are the narrators of the Sahih except Abdul Malik bin Muhammad bin Abdullah, who is thiqah (trustworthy), though there is disagreement about him.
