I saw Messenger of Allah ﷺ on the day of the battle of Uhud accompanied by two men fighting on his behalf. They were dressed in white and were fighting as bravely as possible. I had never seen them before, nor did I see them later on.  

رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَوْمَ أُحُدٍ وَمَعَهُ رَجُلاَنِ يُقَاتِلاَنِ عَنْهُ عَلَيْهِمَا ثِيَابٌ بِيضٌ كَأَشَدِّ الْقِتَالِ مَا رَأَيْتُهُمَا قَبْلُ وَلاَ بَعْدُ
