Sunan At-Tirmidhi

Narrated Abu Hurairah: That the Messenger of Allah (ﷺ) said: ""None is wounded in Allah's cause - and Allah knows better about who has been injured in His cause - except that he will come on the Day of Resurrection with his wound the color of blood but its scent will be the scent of musk."" [Abu 'Eisa said:] This Hadith is Hasan Sahih. It has been reported through other routes from the Prophet (ﷺ)
