Al-Matalib al-'Aliyah 4380 — The killing of Uthman bin Affan

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that Sayyiduna Uthman (may Allah be pleased with him) sought permission to come into the presence of the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) granted him permission. He entered with the fastenings of his garment (lower wrap) undone. The Prophet (peace and blessings be upon him) said: "O Uthman! Come close to me." He came close. Then he (peace and blessings be upon him) said: "O Uthman! Come closer still," until his knees touched the blessed knees of the Prophet (peace and blessings be upon him). Then the Messenger of Allah (peace and blessings be upon him) himself fastened the buttons of his garment with his blessed hand. After that he (peace and blessings be upon him) said: "O Uthman! You will surely come on the Day of Resurrection in such a state that fountains of blood will be gushing from your veins. I will ask: Who did this wrong to you? Then you will name them and complain; among them will be one who incited and commanded, one who was cunning and conspiring, and one who disloyally abandoned you. While you are in this state, suddenly the voice of a caller will be heard from the heavens: Know well! Surely Uthman, despite the (unjust) judgements of his enemies, is a wali (friend) of Allah and a servant close to Him. O Uthman! What will your state be at that time?" He said these words three times: 'La hawla wa la quwwata illa billah' (There is no ability to avoid (evil) nor strength (to do good) except by the will and help of Allah).
This narration is in the Musnad of al-Harith (Bughyat al-Bahith), but because of the presence of narrators such as Dawud bin al-Muhabbar and Hisham bin Ziyad in its chain, it is da'if (weak) in terms of its chain.
