Chapter on Lost Property and Stray Animals

And if the found item (luqata) is less than a dirham, then it belongs to you, and you do not have to announce it. If you find a worn-out dinar in the sacred precinct (Haram), it belongs to you, and you do not have to announce it. If you find food in a desolate place, then estimate its value for yourself on behalf of its owner, and eat it; if its owner comes, return the value to him. If you find a lost item in an inhabited house, then it belongs to its residents; and if it is found in a deserted ruin, then it belongs to whoever finds it.
