Abu Musa Ashari reported,

When the Prophet ﷺ finished the battle of Hunayn, he sent Abu Amir at the head of an army to Awtas. There he met Durayd bin al-Simma, and Durayd was killed and Allah routed his companions.Abu Musa said, "He sent me along with Abu Amir."Abu Amir was struck in the knee by an arrow shot by a man from Banu Jusham, which lodged firmly in his knee. I came up to him and said, "Uncle, who shot you?"Abu Amir pointed to the man and said to Abu Musa, "That one over there is my killer. Do you see him? He is the one who shot me."Abu Musa said, "So I set out after him and pursued him until I caught up with him. When he saw me, he turned and fled. I followed him, calling out, 'Have you no shame? Are you not an Arab? Will you not stand your ground?' So he stopped, and we met and exchanged two blows. I struck him with my sword and killed him.Then I returned to Abu Amir and said, 'Allah has killed your man.'He said, 'Pull out this arrow.'So I pulled it out, and fluid gushed from the wound. He said, 'Nephew, go to the Messenger of Allah ﷺ and convey my greetings of peace to him, and tell him that Abu Amir asks you to seek forgiveness for him.'"Abu Amir put me in command over the men, and he lingered only a short while before he died. When I returned to the Prophet ﷺ, I went in to him while he was in a room on a rope-strung bed with a mattress on it, and the cords of the bed had left marks on the back and sides of the Messenger of Allah ﷺ. I told him our news and the news of Abu Amir, and I said to him, "He told me to ask you to seek forgiveness for him."The Messenger of Allah ﷺ called for water and performed ablution from it, then he raised his hands and said, "O Allah, forgive Ubayd, Abu Amir," until I could see the whiteness of his armpits. Then he said, "O Allah, place him on the Day of Resurrection above many of Your creation," or "above many people."I said, "And for me, Messenger of Allah, ask forgiveness."So the Prophet ﷺ said, "O Allah, forgive Abdullah bin Qays his sin, and admit him on the Day of Resurrection through a noble entrance."Abu Burda said, "One of the two prayers was for Abu Amir, and the other was for Abu Musa."

حدثنا عبد الله بن براد أبو عامر الأشعري وأبو كريب محمد بن العلاء واللفظ لأبي عامر قالا حدثنا أبو أسامة عن بريد

عن أبي بردة عن أبيه قال

لما فرغ النبي ﷺ من حنين بعث أبا عامر على جيش إلى أوطاس فلقي دريد بن الصمة فقتل دريد وهزم الله أصحابه فقال أبو موسى وبعثني مع أبي عامر قال فرمي أبو عامر في ركبته رماه رجل من بني جشم بسهم فأثبته في ركبته فانتهيت إليه فقلت يا عم من رماك فأشار أبو عامر إلى أبي موسى فقال إن ذاك قاتلي تراه ذلك الذي رماني قال أبو موسى فقصدت له فاعتمدته فلحقته فلما رآني ولى عني ذاهبا فاتبعته وجعلت أقول له ألا تستحيي ألست عربيا ألا تثبت فكف فالتقيت أنا وهو فاختلفنا أنا وهو ضربتين فضربته بالسيف فقتلته ثم رجعت إلى أبي عامر فقلت إن الله قد قتل صاحبك قال فانزع هذا السهم فنزعته فنزا منه الماء فقال يا ابن أخي انطلق إلى رسول الله ﷺ فأقرئه مني السلام وقل له يقول لك أبو عامر استغفر لي قال واستعملني أبو عامر على الناس ومكث يسيرا ثم إنه مات فلما رجعت إلى النبي ﷺ دخلت عليه وهو في بيت على سرير مرمل وعليه فراش وقد أثر رمال السرير بظهر رسول الله ﷺ وجنبيه فأخبرته بخبرنا وخبر أبي عامر وقلت له قال قل له يستغفر لي فدعا رسول الله ﷺ بماء فتوضأ منه ثم رفع يديه ثم قال اللهم اغفر لعبيد أبي عامر حتى رأيت بياض إبطيه ثم قال اللهم اجعله يوم القيامة فوق كثير من خلقك أو من الناس فقلت ولي يا رسول الله فاستغفر فقال النبي ﷺ اللهم اغفر لعبد الله بن قيس ذنبه وأدخله يوم القيامة مدخلا كريما قال أبو بردة إحداهما لأبي عامر والأخرى لأبي موسى
