Sunan an-Nasa'i, Book 21, Hadith 186 (In-Book) ⓘ

It was narrated that 'Abdullah bin Tha'labah said: "The Messenger of Allah said, concerning those who had been slain at Uhud: 'Wrap them up on their clothes that are stained with blood, for there is no wound that is sustained for the sake of Allah, but it will come bleeding on the Day of Resurrection: its color will be the color of blood, but its fragrance will be the fragrance of musk."'

أَخْبَرَنَا هَنَّادٌ، عَنِ ابْنِ الْمُبَارَكِ، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنْ عَبْدِ اللَّهِ بْنِ ثَعْلَبَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم لِقَتْلَى أُحُدٍ ‏:‏ ‏ "‏ زَمِّلُوهُمْ بِدِمَائِهِمْ، فَإِنَّهُ لَيْسَ كَلْمٌ يُكْلَمُ فِي اللَّهِ إِلاَّ يَأْتِي يَوْمَ الْقِيَامَةِ يَدْمَى، لَوْنُهُ لَوْنُ الدَّمِ وَرِيحُهُ رِيحُ الْمِسْكِ ‏" ‏ ‏.‏
