Musannaf Ibn Abi Shaybah 40617 — The journey of Aishah, Ali, Talhah

It is reported from al-Hasan: A man came to Sayyiduna al-Zubayr (may Allah be pleased with him) and said: "Shall I kill Ali (may Allah be pleased with him) for you?" Sayyiduna al-Zubayr said: "How?" He replied: "I will go to him and say that I am with him, and then I will kill him by treachery." Sayyiduna al-Zubayr said: "I heard the Messenger of Allah (peace and blessings be upon him) saying: 'Faith restrains treachery, and a believer never commits treachery.'"
