[Machine] Narrated by Ibn Abbas: "The tribe of Aws used to talk about the matters of ignorance and would become angry to the point of war among themselves. So they took up arms and some of them confronted others." Then the verse was revealed: "And how can you disbelieve while the verses of Allah are recited to you and among you is His Messenger? But whoever holds firmly to Allah has [indeed] been guided to a straight path." (Quran 3:101)  

عَنِ ابْنِ عَبَّاسٍ {وَكَيْفَ تَكْفُرُونَ وَأَنْتُمْ تُتْلَى عَلَيْكُمْ آيَاتُ اللهِ وَفِيكُمْ رَسُولُهُ} قَالَ «كَانَ الْأَوْسُ يَتَحَدَّثُونَ إِذْ ذَكَرُوا أَمْرَ الْجَاهِلِيَّةِ فَغَضِبُوا حَتَّى كَانَ بَيْنَهُمْ حَرْبٌ فَأَخَذُوا السِّلَاحَ وَمَشَى بَعْضُهُمْ إِلَى بَعْضٍ» فَنَزَلَتْ {وَكَيْفَ تَكْفُرُونَ وَأَنْتُمْ تُتْلَى عَلَيْكُمْ آيَاتُ اللهِ} إِلَى قَوْلِهِ {فَأَنْقَذَكُمْ مِنْهَا}
