Mishkat al-Masabih 4114 — Game and Animals Which May Be Slaughtered

Jabir Narrated from:

I was on the expedition when the army had to beat leaves off trees for food and Abu ‘Ubaida was placed in charge. We suffered severe hunger, and then the sea cast up a dead fish the like of which we had never seen before, called the spermaceti whale, and we ate of it for half a month. Abu ‘Ubaida took one of its bones and a rider was able to pass under it. When we arrived and mentioned the matter to the Prophet he said, ''Eat a provision which God has brought forth for you, and give us some to eat if you have any." He said they sent some of it to God’s messenger and he ate it. (Bukhari and Muslim.)
