When the Prophet (ﷺ) had finished from the battle of HḤunain, he sent ' Aamir as the head of an army to to fix them. He (i.e. Aamir) met (in a combat against) Duraid bin-Şimma and Duraid was killed, and Allâh defeated his companions. The Prophet (ﷺ) sent me with Aamir. ' Aamir was shot at his knee with an arrow which a man from Jusham had shot and fixed into his knee. I went to him and said, "O uncle ! Who shot you?" He pointed me out (his killer) saying, "That is my killer who shot me (with an arrow)." So I headed towards him and overtook him, and when he saw me, he fled, and I followed him and started saying to him, "Won't you be ashamed? Won't you stop?" So that person stopped and we exchanged two hits with the swords and I killed him. Then I said to Aamir." Allâh has killed your killer." He said, "Take out this arrow." So I removed it, and water oozed out of the wound. He then said, "O son of my brother ! Convey my compliments to the Prophet (ﷺ) and request him to ask Allâh's Forgiveness for me." Aamir made me his successor in commanding the people (i.e. troops). He survived for a short while and then died. (Later) I returned and entered upon the Prophet (ﷺ) at his house, and found him lying in a bed made of stalks of date-palm leaves knitted with ropes, and on it there was bedding. The strings of the bed had their traces over his back and sides. Then I told the Prophet (ﷺ) about our and Aamir's news and he (Aamir) had said, "Tell him (the Prophet ﷺ) to ask for Allâh's Forgiveness for me (Aamir)." The Prophet (ﷺ) asked for water, performed ablution and then raised hands, saying, O Allâh ! Forgive ' Ubaid, Aamir." At that time I saw the whiteness of the Prophet's armpits. The Prophet (ﷺ) then said, "O Allâh, make him (i.e. ' Aamir) on the Day of Resurrection, superior to many of Your human creatures." I said, "Will you ask Allâh's Forgiveness for me? (On that) the Prophet (ﷺ) said, "O Allâh, forgive the sins of 'Abdullâh bin Qais (the name of Mûsa Al-Ash'arî) and admit him to a nice entrance (i.e. Paradise) on the Day of Resurrection." [5:612-O.B]
