It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that he said: "I reached Abu Jahl (on the day of the Battle of Badr) while he was lying on the ground, overcome by wounds, with an iron helmet on his head, and I had an old, worn-out sword. I began striking his head with that sword of mine, and I remembered the time in Makkah when he used to strike me on my head, until his hand grew weak and I seized his sword. Then he raised his head and said (arrogantly): 'Who suffered the defeat? Against us or in our favour? And were you not our little shepherd in Makkah?'" Sayyiduna Abdullah (may Allah be pleased with him) said: "Then I killed him, and I came to the Prophet (peace and blessings be upon him) and said that I had killed Abu Jahl." He (peace and blessings be upon him) asked: "By Allah, besides whom there is no deity worthy of worship, did you really kill him?" He (peace and blessings be upon him) made me swear three times; then he (peace and blessings be upon him) went with me to those (slain men) and supplicated against them.
