Musannaf Ibn Abi Shayba 13:463

Abu Bakr narrated to us, he said: Ibn ‘Ulayyah narrated to us, from Ibn ‘Awn, from Ibn Sirin, who said: Two men came and stood before Shurayh, then they debated. One of them said to him: "Bear witness that I have accepted my camel and thirty dirhams." Shurayh remained silent. He (Ibn Sirin) said: I think that if he had disliked it, he would have rejected it.
