Narrated Jubair bin Mut'im:
I heard the Prophet reciting Surat-at-Tur in Maghrib prayer, and that was at a time when belief was first planted in my heart. The Prophet while speaking about the war prisoners of Badr, said, "Were Al-Mutim bin Adi alive and interceded with me for these filthy people, I would definitely forgive them for his sake." Narrated Said bin Al-Musaiyab: When the first civil strife (in Islam) took place because of the murder of 'Uthman, it left none of the Badr warriors alive. When the second civil strife, that is the battle of Al-Harra, took place, it left none of the Hudaibiya treaty companions alive. Then the third civil strife took place and it did not subside till it had exhausted all the strength of the people.
حَدَّثَنِي إِسْحَاقُ بْنُ مَنْصُورٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ مُحَمَّدِ بْنِ جُبَيْرٍ، عَنْ أَبِيهِ، قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقْرَأُ فِي الْمَغْرِبِ بِالطُّورِ، وَذَلِكَ أَوَّلَ مَا وَقَرَ الإِيمَانُ فِي قَلْبِي.
