حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِي حَازِمٍ، قَالَ حَدَّثَنِي بِمِنًى، عَنْ أَبِيهِ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ الْقَدَرِيَّةُ مَجُوسُ هَذِهِ الأُمَّةِ إِنْ مَرِضُوا فَلاَ تَعُودُوهُمْ وَإِنْ مَاتُوا فَلاَ تَشْهَدُوهُمْ ‏"‏ ‏.‏
Translation
Narrated AbuDharr and AbuHurayrah

The Messenger of Allah (ﷺ) used to sit among his Companions. A stranger would come and not recognize him (the Prophet) until he asked (about him). So we asked the Messenger of Allah (ﷺ) to make a place where he might take his seat so that when a stranger came, he might recognise him. So we built a terrace of soil on which he would take his seat, and we would sit beside him. He then mentioned something similar to this Hadith saying: A man came, and he described his appearance. He saluted from the side of the assembly, saying: Peace be upon you, Muhammad. The Prophet (ﷺ) then responded to him.
