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." (Using translation from Bukhārī 237)
وقَالَ رَسُولُ اللهِ ﷺ كُلُّ كَلْمٍ يُكْلَمُهُ الْمُسْلِمُ فِي سَبِيلِ اللهِ يَكُونُ يَوْمَ الْقِيَامَةِ كَهَيْئَتِهَا إِذَا طُعِنَتْ تَفَجَّرُ دَمًا فَاللَّوْنُ لَوْنُ الدَّمِ وَالْعَرْفُ عَرْفُ الْمِسْكِ
