Wounds in Allah’s Cause on the Day of Resurrection
Narrated Abu Huraira:
The Prophet 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.”
Translation of Sahih Bukhari, Volume 1, Book 4, Number 238
