[Machine] Abdullah ibn Mas'ood approached Abu Jahl on the day of Badr while Abu Jahl was tied up. He asked for his sword and struck his neck, decapitating him. He then took his belongings and went to the Prophet ﷺ to inform him that he had killed Abu Jahl. The Prophet ﷺ made him swear by Allah three times, and he swore, so the Prophet gave him his belongings.
«انْتَهَى عَبْدُ اللهِ بْنُ مَسْعُودٍ إِلَى أَبِي جَهْلٍ يَوْمَ بَدْرٍ وَهُوَ وَقِيذٌ فَاسْتَلَّ سَيْفَهُ فَضَرَبَ عُنُقَهُ فَبَدَرَ رَأْسَهُ ثُمَّ أَخَذَ سَلَبَهُ وَأَتَى النَّبِيَّ ﷺ فَأَخْبَرَهُ أَنَّهُ قَتَلَ أَبَا جَهْلٍ فأَحْلَفَهُ بِاللهِ ثَلَاثَ مَرَّاتٍ فَحَلَفَ فَجَعَلَ لَهُ سَلَبَهُ»
