Musannaf Ibn Abi Shayba 13:2038

Abu Bakr narrated to us, he said: Waki’ narrated to us, he said: Sufyan narrated to us, from ‘Abd al-‘Aziz ibn Rufay’, from ‘Abd Allah ibn Abi Mulaykah, from ‘Abd Allah ibn Hanzalah ibn al-Rahib, from Ka’b al-Ahbar, who said: "That I should commit adultery thirty-three times is more beloved to me than that I should consume a dirham of usury (riba), while Allah knows that I consumed it when I consumed it, and it is usury."
