Abu Jahl was the worst and most bitter enemy of Islam and Prophet Muhammad (peace be upon him). He oppressed believers greatly. His real name was Amr bin Hisham and belonged to Quraish, the tribe to which Prophets clan – Bani Hashim belonged. Abu Jahl was a polytheist and worshiped idols. He was among very influential people during the era of ignorance. Prophet Muhammad (peace be upon him) used to supplicate to Allah that one of the two Omars ( Amr- bin hisam or Omar ibn Khattab(RA) ) would accept Islam and it was Omar ibn-Khattab(Radiallahuanhu) who was blessed with the deen of Allah while Abu Jahl persisted with his paganism.
ABU JAHAL was killed in the great battle of Badr near Medina, having proven to be an equal in aggression and vice to the Pharaoh of Egypt.
He was killed by two young boys namely Muadh bin ‘Afra and Muadh bin Amr bin Al-Jamuh (radiallaahu `anhumaa).
The following narration holds the proof to it.
Volume 4, Book 53, Number 369 :
Narrated by ‘Abdur-Rahman bin ‘Auf (radiallaahu `anhu)
While I was standing in the row on the day (of the battle) of Badr, I looked to my right and my left and saw two young Ansari boys, and I wished I had been stronger than they. One of them called my attention saying, “O Uncle! Do you know Abu Jahl?” I said, “Yes, What do you want from him, O my nephew?” He said, “I have been informed that he abuses Allah’s Apostle (sallallaahu `alayhi wasallam). By Him in Whose Hands my life is, if I should see him, then my body will not leave his body till either of us meet his fate.” I was astonished at that talk. Then the other boy called my attention saying the same as the other had said. After a while I saw Abu Jahl walking amongst the people. I said (to the boys), “Look! This is the man you asked me about.” So, both of them attacked him with their swords and struck him to death and returned to Allah’s Apostle (sallallaahu `alayhi wasallam) to inform him of that. Allah’s Apostle (sallallaahu `alayhi wasallam) asked, “Which of you has killed him?” Each of them said, “I have killed him.” Allah’s Apostle (sallallaahu `alayhi wasallam) asked, “Have you cleaned your swords?” They said, “No.” He then looked at their swords and said, “No doubt, you both have killed him and the spoils of the deceased will be given to Muadh bin Amr bin Al-Jamuh.” The two boys were Muadh bin ‘Afra and Muadh bin Amr bin Al-Jamuh (radiallaahu `anhumaa).
May Allah curse the enemies of Islam.
