Sayyiduna Salamah bin al-Akwa' (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "May Allah Almighty keep the people of the tribe of Aslam safe, and may Allah Almighty forgive the people of the tribe of Ghifar. It is not I who am saying this; rather, Allah Almighty has said it."
Ahmad and al-Tabarani recorded it; its chain contains Umar bin Rashid al-Yamami, whom al-'Ijli declared thiqah (trustworthy) while the majority declared him da'if (weak). The remaining narrators of both are the narrators of the Sahih.
