Muti' said, "I heard the Prophet, may Allah bless him and grant him peace, say on the day of the Conquest of Makka, 'No Qurayshi will be killed in custody from today until the Day of Rising.'" None of the rebels of Quraysh except Muti' became Muslim. His name had been al-'As and the Prophet, may Allah bless him and grant him peace, renamed him Muti' (obedient).

حَدَّثَنَا مُسَدَّدٌ، قَالَ: حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ زَكَرِيَّا قَالَ: حَدَّثَنِي عَامِرٌ، عَنْ عَبْدِ اللهِ بْنِ مُطِيعٍ قَالَ: سَمِعْتُ مُطِيعًا يَقُولُ: سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ، يَوْمَ فَتْحِ مَكَّةَ: لاَ يُقْتَلُ قُرَشِيٌّ صَبْرًا بَعْدَ الْيَوْمِ إِلَى يَوْمِ الْقِيَامَةِ، فَلَمْ يُدْرِكِ الإِسْلاَمَ أَحَدٌ مِنْ عُصَاةِ قُرَيْشٍ غَيْرُ مُطِيعٍ، كَانَ اسْمُهُ الْعَاصَ فَسَمَّاهُ النَّبِيُّ صلى الله عليه وسلم مُطِيعًا.
