Musannaf Ibn Abi Shaybah 40456 — Reports on Uthman (may Allah be)

It is narrated from Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both) that he said: I said to Sayyiduna Uthman (may Allah be pleased with him) on the day of (the siege of) the House: Go out and fight them. Indeed, you have with you those to whom Allah Almighty has given help in smaller numbers than this. By Allah, fighting them is lawful. He said: Sayyiduna Uthman refused, and said: Whoever owes me hearing and obedience, let him obey Abdullah bin al-Zubayr. Sayyiduna Uthman had appointed him as commander over the house that day, and Sayyiduna Uthman was fasting that day.
