Musannaf Ibn Abi Shayba 9:1576

Affan narrated to us, he said: Aban al-Attar narrated to us, he said: Yahya ibn Abi Kathir narrated to me, from Ibrahim ibn Qariz, from al-Sa’ib ibn Yazid, from Rafi’ ibn Khadij, that the Prophet, may Allah bless him and grant him peace, said: "The earnings of the cupper are foul, and the dowry of the prostitute is foul."
