Anas reported the Messenger of Allaah(ﷺ) as saying “He who kills and infidel gets his spoil.” Abu Talhah killed twenty men that day meaning the day of Hunain and got their spoils. Abu Talhah met Umm Sulaim who had a dagger with her. He asked “What is with you, Umm Sulaim”? She replied “I swear by Allaah, I intended that if anyone came near me I would pierce his belly with it. Abu Talhah informed the Messenger of Allaah(ﷺ)about it. Abu Dawud said “This is good (hasan) tradition." Abu Dawud said “By this was meant dagger. The weapon used by the Non – Arabs in those days was dagger.”

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَوْمَئِذٍ - يَعْنِي يَوْمَ حُنَيْنٍ - ‏

‏ مَنْ قَتَلَ كَافِرًا فَلَهُ سَلَبُهُ ‏

‏ ‏.‏ فَقَتَلَ أَبُو طَلْحَةَ يَوْمَئِذٍ عِشْرِينَ رَجُلاً وَأَخَذَ أَسْلاَبَهُمْ وَلَقِيَ أَبُو طَلْحَةَ أُمَّ سُلَيْمٍ وَمَعَهَا خِنْجَرٌ فَقَالَ يَا أُمَّ سُلَيْمٍ مَا هَذَا مَعَكِ قَالَتْ أَرَدْتُ وَاللَّهِ إِنْ دَنَا مِنِّي بَعْضُهُمْ أَبْعَجُ بِهِ بَطْنَهُ ‏.‏ فَأَخْبَرَ بِذَلِكَ أَبُو طَلْحَةَ رَسُولَ اللَّهِ صلى الله عليه وسلم ‏.‏ قَالَ أَبُو دَاوُدَ هَذَا حَدِيثٌ حَسَنٌ ‏.‏ قَالَ أَبُو دَاوُدَ أَرَدْنَا بِهَذَا الْخِنْجَرَ وَكَانَ سِلاَحَ الْعَجَمِ يَوْمَئِذٍ الْخِنْجَرُ ‏.‏
