حَدَّثَنِي هَنَّادُ بْنُ السَّرِيِّ، عَنْ أَبِي بَكْرٍ، عَنْ عَاصِمٍ، عَنْ مُصْعَبِ بْنِ سَعْدٍ، عَنْ أَبِيهِ، قَالَ جِئْتُ إِلَى النَّبِي صلى الله عليه وسلم يَوْمَ بَدْرٍ بِسَيْفٍ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنَّ اللَّهَ قَدْ شَفَى صَدْرِي الْيَوْمَ مِنَ الْعَدُوِّ فَهَبْ لِي هَذَا السَّيْفَ ‏.‏ قَالَ ‏"‏إِنَّ هَذَا السَّيْفَ لَيْسَ لِي وَلاَ لَكَ ‏"‏ فَذَهَبْتُ وَأَنَا أَقُولُ يُعْطَاهُ الْيَوْمَ مَنْ لَمْ يُبْلِ بَلاَئِي ‏.‏ فَبَيْنَا أَنَا إِذْ جَاءَنِي الرَّسُولُ فَقَالَ أَجِبْ ‏.‏ فَظَنَنْتُ أَنَّهُ نَزَلَ فِيَّ شَىْءٌ بِكَلاَمِي فَجِئْتُ فَقَالَ لِي النَّبِيُّ صلى الله عليه وسلم ‏"‏ إِنَّكَ سَأَلْتَنِي هَذَا السَّيْفَ وَلَيْسَ هُوَ لِي وَلاَ لَكَ وَإِنَّ اللَّهَ قَدْ جَعَلَهُ لِي فَهُوَ لَكَ ثُمَّ قَرَأَ ‏‏{‏ يَسْأَلُونَكَ عَنِ الأَنْفَالِ قُلِ الأَنْفَالُ لِلَّهِ وَالرَّسُولِ ‏}‏ إِلَى آخِرِ الآيَةِ‏"‏ ‏.‏ قَالَ أَبُو دَاوُدَ قِرَاءَةُ ابْنِ مَسْعُودٍ يَسْأَلُونَكَ النَّفْلَ

I came to the Prophet (ﷺ) on the day of Badr with a sword and said, "O Messenger of Allah, Allah has indeed healed my chest today from the enemy, so give me this sword." He said, "This sword is neither mine nor yours." So I went away, saying, "He will give it today to someone who has not shown the steadfastness I have." While I was thus, a messenger came to me and said, "Respond." I thought something had been revealed regarding me because of what I had said. So I came, and the Prophet (ﷺ) said to me, "You asked me for this sword and it was neither mine nor yours, and now Allah has granted it to me, so it is yours." Then he recited:

"They ask you concerning the spoils of war. Say, 'The spoils are for Allah and the Messenger...'"

to the end of the verse. Abu Dawud said: The reading of Ibn Mas'ud is: "They ask you concerning the nafl (spoils)."
