One who is wounded in the way of Allah-and Allah knows better who is wounded in His way-will appear on the Day of Judgment with his wound bleediing. The colour (of its discharge) will be the colour of blood, (but) its smell will be the smell of musk. (Using translation from Muslim 1876d)  

عَنِ النَّبِيِّ ﷺ قَالَ «لَا يُكْلَمُ أَحَدٌ فِي سَبِيلِ اللهِ وَاللهُ أَعْلَمُ بِمَنْ يُكْلَمُ فِي سَبِيلِهِ إِلَّا جَاءَ يَوْمَ الْقِيَامَةِ وَجُرْحُهُ يَثْعَبُ دَمًا اللَّوْنُ لَوْنُ دَمٍ وَالرِّيحُ رِيحُ الْمِسْكِ»  

"The Messenger of Allah ﷺ said: 'Wrap them up with their blood, for there is no wound incurred in the cause of Allah, but he will come on the Day of Resurrection bleeding with the color of blood, but its fragrance will be that of musk.'" (Using translation from Nasāʾī 3148)  

قَالَ رَسُولُ اللهِ ﷺ «زَمِّلُوهُمْ بِدِمَائِهِمْ فَإِنَّهُ لَيْسَ كَلْمٌ يُكْلَمُ فِي اللهِ إِلَّا أَتَى يَوْمَ الْقِيَامَةِ جُرْحُهُ يَدْمَى لَوْنُهُ لَوْنُ دَمٍ وَرِيحُهُ رِيحُ الْمِسْكِ»
