Musannaf Ibn Abi Shayba 13:2989

Abu Bakr narrated to us, he said: Khalid bin al-Harith narrated to us, from Abu Makin, that Abu Mijlaz and Yahya bin Aqil—one of them said: "A man betrayed me and took a dirham from me, and he now has dirhams of mine in his possession. Should I not take from his dirhams just as he took from my dirhams?" He said to me: "Do not take, so that I do not take." The one who was taking said: "But I will take."
