Abd ibn Humayd and Hajjaj ibn al-Sha’ir narrated to us, both of them from Abu al-Walid. Abd said: Abu al-Walid narrated to me, saying: Ishaq ibn Sa’id ibn ‘Amr ibn Sa’id ibn al-‘As narrated to us, saying: My father narrated to me, from his father, who said: I was with ‘Uthman when he called for water for ablution, and he said: I heard the Messenger of Allah, peace and blessings be upon him, say: “There is no Muslim man who, when an obligatory prayer comes due, performs its ablution, humility, and bowing well, except that it will be an expiation for the sins committed before it, as long as he has not committed a major sin—and that applies for all time.”
