Al-Mu'jam al-Awsat 6003 — Sayyiduna Uthman came to the Prophet ﷺ

The Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), narrates: "Sayyiduna Uthman (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him) and spoke with him (peace and blessings be upon him) privately for a long time, while I was at some distance from them both. Then suddenly I saw Sayyiduna Uthman (may Allah be pleased with him) kneeling on his knees, saying: 'O Messenger of Allah! Will (it happen) through injustice and aggression?' So I thought that he (peace and blessings be upon him) had informed him of his being killed."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith except Abu Sa'id al-Mu'addib Muhammad bin Muslim bin Abi al-Waddah, and Mansur bin Abi Muzahim is alone in narrating it."
