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.
عَنِ النَّبِيِّ ﷺ قَالَ لاَ يُكْلَمُ أَحَدٌ فِي سَبِيلِ اللَّهِ وَاللَّهُ أَعْلَمُ بِمَنْ يُكْلَمُ فِي سَبِيلِهِ إِلاَّ جَاءَ يَوْمَ الْقِيَامَةِ وَجُرْحُهُ يَثْعَبُ اللَّوْنُ لَوْنُ دَمٍ وَالرِّيحُ رِيحُ مِسْكٍ
