Narrated By Abu Huraira (RA) : Allah’s(SWT) Apostle(PBUH) said, “By Him in Whose Hands my soul is! Whoever is wounded in Allah’s(SWT) Cause… and Allah(SWT) knows well who gets wounded in His Cause… will come on the Day of Resurrection with his wound having the colour of blood but the scent of musk.”
Sahih Bukhari Hadith No: 2804
