Narrated Abu Huraira:
حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدٍ ، قَالَ أَخْبَرَنَا عَبْدُ اللَّهِ ، قَالَ أَخْبَرَنَا مَعْمَرٌ ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ ، عَنْ أَبِي هُرَيْرَةَ ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " كُلُّ كَلْمٍ يُكْلَمُهُ الْمُسْلِمُ فِي سَبِيلِ اللَّهِ يَكُونُ يَوْمَ الْقِيَامَةِ كَهَيْئَتِهَا إِذْ طُعِنَتْ، تَفَجَّرُ دَمًا، اللَّوْنُ لَوْنُ الدَّمِ، وَالْعَرْفُ عَرْفُ الْمِسْكِ " .
The Prophet (ﷺ) said, "A wound which a Muslim receives in Allah's cause will appear on the Day of Resurrection as it was at the time of infliction; blood will be flowing from the wound and its color will be that of the blood but will smell like musk."
