Musannaf Ibn Abi Shayba 9:1579

Abu Mu'awiyah narrated to us, from al-A'mash, from Abu Sufyan, from Jabir, regarding His saying: "And whoever compels them, then indeed, Allah, after their compulsion, is Forgiving, Merciful." He said: Abdullah ibn Ubayy ibn Salul used to say to his slave girl, "Go and earn for us something." Then Allah the Exalted revealed: "And do not compel your slave girls to prostitution, if they desire chastity, to seek the temporary interests of worldly life. And whoever compels them, then indeed, Allah, after their compulsion, is Forgiving, Merciful."
