Musnad Ahmad Hadith 3801

I came to Abu Jahl when he had been wounded and his foot had been cut off, and I started striking him with my sword but it did not do anything to him - it was said to Shareek in the hadeeth: Did he try to ward him off with his sword? He said: Yes - He said: So I carried on until I took his sword and struck him with it, until I killed him. Then I went to the Prophet (ﷺ) and said: Abu Jahl has been killed - Perhaps Shareek said: I have killed Abu Jahl - and he said: “Did you see him?” I said: Yes. He said: "Do you swear by Allah?" twice. I said: Yes. He said: "Then let us go so that I can look at him." He went to him and the sun had changed him somewhat, so he ordered that he and his companions be dragged and thrown into the dry well, then he followed the people of the well with a curse and said: “This was the pharaoh of this nation.”
