ذِكْرُ دُعَاءِ الْمُصْطَفَى ﷺ لِأَبِي مُوسَى بِمَغْفِرَةِ ذُنُوبِهِ
He (the Holy Prophet) sent me along with Abu 'Amir and Abu 'Amir received a wound in his knee from the arrow, (shot by) a person of Bani Jusham. It stuck in his knee. I went to him and said: Uncle, who shot an arrow upon you? Abu 'Amir pointed out to Abu Musa and said: Verily that one who shot an arrow upon me in fact killed me. Abu Musa said: I followed him with the determination to kill him and overtook him and when he saw me he turned upon his heels. I followed him and I said to him: Don't you feel ashamed (that you run), aren't you an Arab? Why don't you stop? He stopped and I had an encounter with him and we exchanged the strokes of (swords). I struck him with the sword and killed him. Then I came back to Abu Amir and said: Verily Allah has killed the one who killed you. And he said: Now draw out this arrow. I drew out the arrow and there came out from that (wound) water. Abu 'Amir said: My nephew, go to Messenger of Allah ﷺ and convey my greetings to him and tell him that Abu Amir begs you to ask forgiveness for him. And Abu Amir appointed me as the chief of the people and he died after a short time. When I came to Allah's Apostle ﷺ I visited him and he had been lying on the cot woven by strings and there was (no) bed over it and so there had been marks of the strings on the back of Messenger of Allah ﷺ and on his sides. I narrated to him what had happened to us and narrated to him about Abu Amir and said to him that he had made a request to the effect that forgiveness should be sought for him (from Allah). Thereupon Messenger of Allah (may peace be. upon him) called for water and performed ablution with it. He then lifted his hands and said. O Allah, grant pardon to Thy servant Abu Amir. (The Prophet had raised his hands so high for supplication) that I saw the whiteness of his armpits. He again said: O Allah, grant him distinction amongst the majority of Thine created beings or from amongst the people. I said: Messenger of Allah, ask forgiveness for me too. Thereupon Allah's Apostle ﷺ said: Allah, forgive the sins of Abdullah b. Qais (Abu Musa Ash'ari) and admit him to an elevated place on the Day of Resurrection. Abu Burda said: One prayer is for abu 'Amir and the other is tor Abu Musa. (Using translation from Muslim 2498)
لَمَّا فَرَغَ رَسُولُ اللَّهِ ﷺ مِنْ حُنَيْنٍ بَعَثَ أَبَا عَامِرٍ عَلَى جَيْشٍ إِلَى أَوْطَاسَ فَلَقِيَ دُرَيْدَ بْنَ الصِّمَّةِ فَقَتَلَ دُرَيْدًا وَهَزَمَ اللَّهُ أَصْحَابَهُ وَرُمِيَ أَبُو عَامِرٍ فِي رُكْبَتِهِ رَمَاهُ رَجُلٌ مِنْ بَنِي جُشَمٍ بِسَهْمٍ فَأَثْبَتَهُ فِي رُكْبَتِهِ فَانْتَهَيْتُ إِلَيْهِ فَقُلْتُ يَا عَمِّ مَنْ رَمَاكَ؟ فَأَشَارَ إِلَى أَنْ ذَاكَ قَاتِلِي يُرِيدُ ذَلِكَ الَّذِي رَمَانِي قَالَ أَبُو مُوسَى فَقَصَدْتُ لَهُ فَلَحِقْتُهُ فَلَمَّا رَآنِي وَلَّى عَنِّي ذَاهِبًا فَاتَّبَعْتُهُ وَجَعَلْتُ أَقُولُ أَلَا تَسْتَحِي أَلَا تَثْبُتُ؟ أَلَا تَسْتَحِي أَلَسْتَ عَرَبِيًّا؟ فَكَفَّ فَالْتَقَيْتُ أَنَا وَهُوَ فَاخْتَلَفْنَا فَضَرَبْتُهُ بِالسَّيْفِ فَقَتَلْتُهُ ثُمَّ رَجَعْتُ فَقُلْتُ قَدْ قَتَلَ اللَّهُ صَاحِبِكَ قَالَ فَانْزِعْ هَذَا السَّهْمَ فَنَزَعْتُهُ فَنَزَلَ مِنْهُ الْمَاءُ فَقَالَ يَا ابْنَ أَخِي انْطَلِقْ إِلَى رَسُولِ اللَّهِ ﷺ فَأَقْرِئْهُ مِنِّي السَّلَامَ وَقُلْ لَهُ يَقُولُ لَكَ اسْتَغْفِرْ لِي قَالَ وَاسْتَخْلَفَنِي أَبُو عَامِرٍ وَمَكَثَ يَسِيرًا ثُمَّ إِنَّهُ مَاتَ فَلَمَّا رَجَعْتُ إِلَى رَسُولِ اللَّهِ ﷺ فَدَخَلْتُ عَلَيْهِ وَهُوَ فِي بَيْتٍ عَلَى سَرِيرٍ وَقَدْ أَثَّرَ السَّرِيرُ بِظَهْرِ رَسُولِ اللَّهِ ﷺ وَجَنْبَيْهِ فَأَخْبَرْتُهُ خَبَرَنَا وَخَبَرَ أَبَى عَامِرٍ وَقُلْتُ لَهُ إِنَّهُ قَالَ قُلْ لَهُ يَسْتَغْفِرْ لِي قَالَ فَدَعَا رَسُولُ اللَّهِ ﷺ بِمَاءٍ فَتَوَضَّأَ مِنْهُ وَرَفَعَ يَدَيْهِ ثُمَّ قَالَ «اللَّهُمَّ اغْفِرْ لِعُبَيْدٍ أَبِي عَامِرٍ اللَّهُمَّ اجْعَلْهُ يَوْمَ الْقِيَامَةِ فَوْقَ كَثِيرٍ مِنْ خَلْقِكَ» فَقُلْتُ وَلِي يَا رَسُولَ اللَّهِ فَاسْتَغْفِرْ فَقَالَ رَسُولُ اللَّهِ ﷺ «اللَّهُمَّ اغْفِرْ لِعَبْدِ اللَّهِ بْنِ قَيْسٍ ذَنْبَهُ وَأَدْخِلْهُ مُدْخَلًا كَرِيمًا» قَالَ أَبُو بُرْدَةَ أَحَدُهُمَا لِأَبِي عَامِرٍ وَأَحَدُهُمَا لِأَبِي مُوسَى
