[Machine] The Messenger of Allah ﷺ passed by Mus'ab ibn 'Umair when he returned from Uhud and stood in front of him and his companions. He said, "I bear witness that you are alive with Allah, so return their greetings and send blessings upon them. By the One in whose hand is the soul of Muhammad, they will not send greetings upon him, except that he will reply to them until the Day of Resurrection."  

مَرَّ رَسُولُ اللهِ ﷺ عَلَى مُصْعَبِ بْنِ عُمَيْرٍ حِينَ رَجَعَ مِنْ أُحُدٍ فَوَقَفَ عَلَيْهِ وَعَلَى أَصْحَابِهِ فَقَالَ «أَشْهَدُ أَنَّكُمْ أَحْيَاءُ عِنْدَ اللهِ فَرُدُّوهُمْ وَصَلُّوا عَلَيْهِمْ فَوَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَا يُسَلِّمُ عَلَيْهِمْ إِلَّا رَدُّوا عَلَيْهِ إِلَى يَوْمِ الْقِيَامَةِ»
