"No one is wounded in the cause of Allah - and Allah knows best who is wounded in His cause - but he will come on the Day of Resurrection with his wounds bleeding the color of blood, but with the fragrance of musk." (Using translation from Nasāʾī 3147)
عَنِ النَّبِيِّ ﷺ قَالَ مَنْ يُكْلَمُ فِي سَبِيلِ اللهِ وَاللهُ أَعْلَمُ بِمَنْ يُكْلَمُ فِي سَبِيلِهِ يَجِيءُ يَوْمَ الْقِيَامَةِ لَوْنُ جُرْحِهِ لَوْنُ الدَّمِ وَرِيحُهُ رِيحُ الْمِسْكِ
