Abdur Rahman bin Abi Bakr (may Allah be pleased with him) and others narrated from Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him), who said: Umayyah bin Khalaf was my friend in Makkah, and in the days of ignorance my name was Abd Amr. When I became Muslim, I changed my name to Abdur Rahman. When he met me in Makkah, he would say: “Do you not like the name your parents gave you?” I would say: “Yes.” Then he would say: “Well, I do not know this ‘Abdur Rahman’. Just tell me a special name by which I can call you. I don’t know what’s with you that when I call you Abd Amr, you don’t even answer me, and I have no trouble calling you by a name I recognize.” He said: I said, “O Abu Ali! Call me whatever you wish.” He said: “I will call you ‘Abd al-Ilah’.” (That is, he named you ‘Abd al-Ilah’.) On the day of the Battle of Badr, I passed by him while he was standing holding his son Ali’s hand. And I had some armors which I had taken from the disbelievers. When he saw me, he said: “O Abd Amr!” I did not answer. He said: “O Abd al-Ilah!” I said: “Yes.” He said: “I am better for you than these armors.” I said: “Yes.” So I threw the armors from my hand and took hold of his and his son’s hand.
