Sunan an-Nasa'i, Hadith 3147 ⓘ
It was narrated from Abu Hurairah that the Prophet said: "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."
أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لاَ يُكْلَمُ أَحَدٌ فِي سَبِيلِ اللَّهِ - وَاللَّهُ أَعْلَمُ بِمَنْ يُكْلَمُ فِي سَبِيلِهِ - إِلاَّ جَاءَ يَوْمَ الْقِيَامَةِ وَجُرْحُهُ يَثْعَبُ دَمًا اللَّوْنُ لَوْنُ دَمٍ وَالرِّيحُ رِيحُ الْمِسْكِ " .
