Musannaf Ibn Abi Shaybah 29942 — Concealing a thief's offence

Ikrimah says that Sayyiduna Ibn Abbas (may Allah be pleased with them both), Sayyiduna Ammar and Sayyiduna al-Zubayr (may Allah be pleased with them) caught a thief and then let him go. I said to Sayyiduna Ibn Abbas (may Allah be pleased with them both): "You all did wrong when you let him go!" At this he said: "May your mother perish! If you had been in his place, you would surely have wished to be let go."
