Sahih al-Bukhari 4023
Narrated Jubair bin Mut'im:
I heard the Prophet (ﷺ) reciting Surat-at-Tur in Maghrib prayer, and that 
     was at a time when belief was first planted in my heart. The Prophet (ﷺ) 
     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."
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.‏
