Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: “Allah has taken it upon Himself to guarantee the man who goes out in His path, and (Allah says that) when this man goes out only for striving in My path, believing in Me, and affirming My Messenger, then I also guarantee that I will admit him into Paradise, or return him to his home with reward or booty, whatever he has obtained. (Then the Prophet, peace and blessings be upon him, said:) By the One in Whose hand is my soul! Any wound that is inflicted in the path of Allah, the wounded person will come on the Day of Resurrection in the same state as when he was wounded; the color of the flowing blood will be the same as that of blood, but its fragrance will be like that of musk. By the One in Whose hand is the soul of Muhammad! If it were not hard upon the Muslims, I would never stay behind any expedition fighting in the path of Allah, but I do not have the means to take them all with me, and they do not like to stay behind from me. By the One in Whose hand is the soul of Muhammad! I wish that I fight in the path of Allah and be killed, then (be brought back to life and) fight again and be killed, then (be brought back to life and) fight again and be killed.”
