It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) said:

“There is no one who is wounded in the cause of Allah – and Allah knows best of who is wounded in His cause – but he will come on the Day of Resurrection with his wounds looking as they did on the day he was wounded; their color will be the color of blood but their smell will be the fragrance of musk.”

حَدَّثَنَا بِشْرُ بْنُ آدَمَ، وَأَحْمَدُ بْنُ ثَابِتٍ الْجَحْدَرِيُّ، قَالاَ حَدَّثَنَا صَفْوَانُ بْنُ عِيسَى، حَدَّثَنَا مُحَمَّدُ بْنُ عَجْلاَنَ، عَنِ الْقَعْقَاعِ بْنِ حَكِيمٍ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏

‏ مَا مِنْ مَجْرُوحٍ يُجْرَحُ فِي سَبِيلِ اللَّهِ - وَاللَّهُ أَعْلَمُ بِمَنْ يُجْرَحُ فِي سَبِيلِهِ - إِلاَّ جَاءَ يَوْمَ الْقِيَامَةِ وَجُرْحُهُ كَهَيْئَتِهِ يَوْمَ جُرِحَ وَاللَّوْنُ لَوْنُ دَمٍ وَالرِّيحُ رِيحُ مِسْكٍ ‏
