Abu Hurairah reported,
The Prophet ﷺ said, "No one is wounded in the cause of Allah, and Allah knows best who is truly wounded in His cause, except that he will come on the Day of Resurrection with his wound gushing blood. The color will be the color of blood, but the scent will be the scent of musk."
