Yahya bin Sa'id (may Allah have mercy on him) narrates from Sa'id bin al-Musayyib (may Allah have mercy on him) concerning the saying of Allah Almighty: "Indeed, He is ever Forgiving to those who often turn back (to Him)." [Surah al-Isra: 25] He said: A servant sins and then repents, then sins and then repents. (He said:) And I heard him saying that the verse "The fornicator does not marry except a fornicatress or a polytheist woman" [Surah al-Nur: 3] was abrogated by this verse: "And marry the unmarried among you and the righteous among your male slaves and female slaves." [Surah al-Nur: 32]
