The Messenger of Allah (ﷺ) said: If anyone fights in Allah’s path as long as the time between two milkings of a she-camel, Paradise will be assured for him. If anyone sincerely asks Allah for being killed and then dies or is killed, there will be a reward of a martyr for him. Ibn al-Musaffa added from here: If anyone is wounded in Allah’s path, or suffers a misfortune, it will come on the Day of resurrection as copious as possible, its colour saffron, and its odour musk; and if anyone suffers from ulcers while in Allah’s path, he will have on him the stamp of the martyrs.
