Some people eat leftover foods in restaurants, is it permissible to do so?
بسم الله الرحمن الرحيم
(Fatwa: 316/306/N=04/1437)
If the leftover foods of the restaurants are halal and pure as well as it is permitted by the owner directly or indirectly, then you may eat, it is not haram.
Allah knows Best!
