Musnad Abi Ya'la 4805 — the Messenger of Allah ﷺ said: Call one of my

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Call one of my Companions to me." I said: Shall I call Sayyiduna Abu Bakr (may Allah be pleased with him)? He (peace and blessings be upon him) said: "No." I said: Sayyiduna Umar (may Allah be pleased with him)? He (peace and blessings be upon him) said: "No." I said: Shall I call your cousin, Sayyiduna Ali (may Allah be pleased with him)? He (peace and blessings be upon him) said: "No." I asked: Then whom shall I call? He (peace and blessings be upon him) said: "Sayyiduna Uthman (may Allah be pleased with him)." So when he came, he (peace and blessings be upon him) said to me: "Move aside." Then he (peace and blessings be upon him) began speaking to him privately, and meanwhile the colour of Sayyiduna Uthman's (may Allah be pleased with him) face began to change. Abu Sahlah (may Allah have mercy on him) said: Then, on the Day of the House (the day of the siege), when he was besieged, we said: O Commander of the Faithful, will you not fight them? Sayyiduna Uthman (may Allah be pleased with him) said: "Indeed, the Messenger of Allah (peace and blessings be upon him) made a covenant (a binding instruction) with me, and I am keeping myself patient and steadfast upon it."
