[Machine] I heard the Messenger of Allah, ﷺ , on the day of the conquest of Mecca, saying, "No Qurayshi shall be killed after this day except for a just cause until the Day of Resurrection." And no one from the disobedient Quraysh embraced Islam except in obedience, and his name was Al-Aas. So the Messenger of Allah, ﷺ , named him Mu'ti'.
سَمِعْتُ رَسُولَ اللهِ ﷺ يَوْمَ فَتْحِ مَكَّةَ يَقُولُ «لَا يُقْتَلُ قُرَشِيٌّ صَبْرًا بَعْدَ هَذَا الْيَوْمِ إِلَى يَوْمِ الْقِيَامَةِ» وَلَمْ يُدْرِكْ أَحَدٌ الْإِسْلَامَ مِنْ عُصَاةِ قُرَيْشٍ غَيْرَ مُطِيعٍ وَكَانَ اسْمُهُ الْعَاصِ فَسَمَّاهُ رَسُولُ اللهِ ﷺ مُطِيعًا
