Zuhayr ibn Harb and ʿAbd ibn Humayd narrated to me—Zuhayr said: Yaʿqūb ibn Ibrāhīm narrated to us, Ibn Akhī Ibn Shihāb narrated to us, from his uncle, Saʿīd ibn al-Musayyab narrated to me, from Abū Hurayrah, that he said: I heard the Messenger of Allah, peace and blessings be upon him, say: "O Allah, I have taken a covenant with You that You will not break it for me, so any believer whom I have insulted or struck, make that an expiation for him on the Day of Resurrection."
