It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) said:“There is no one who is wounded in the cause of Allah – and Allah knows best of who is wounded in His cause – but he will come on the Day of Resurrection with his wounds looking as they did on the day he was wounded; their color will be the color of blood but their smell will be the fragrance of musk.”
