Musannaf Ibn Abi Shayba 9:1024

Waki' narrated to us, from Salamah, from al-Dahhak, regarding His saying: "The fornicator does not marry except a fornicatress or an idolatress, and the fornicatress does not marry except a fornicator or an idolater." He said: He does not commit fornication when he commits it except with a fornicatress, and she does not commit fornication when she commits it except with a fornicator like her.
