Sahih al-Bukhari, Book 72, Hadith 59 (In-Book) ⓘ

Narrated Abu Huraira: Allah's Messenger said, "None is wounded in Allah's Cause but will come on the Day of Resurrection with his wound bleeding. The thing that will come out of his wound will be the color of blood, but its smell will be the smell of musk."

حَدَّثَنَا مُسَدَّدٌ، عَنْ عَبْدِ الْوَاحِدِ، حَدَّثَنَا عُمَارَةُ بْنُ الْقَعْقَاعِ، عَنْ أَبِي زُرْعَةَ بْنِ عَمْرِو بْنِ جَرِيرٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَا مِنْ مَكْلُومٍ يُكْلَمُ فِي اللَّهِ إِلاَّ جَاءَ يَوْمَ الْقِيَامَةِ وَكَلْمُهُ يَدْمَى، اللَّوْنُ لَوْنُ دَمٍ وَالرِّيحُ رِيحُ مِسْكٍ ‏" ‏‏.‏
