Is winning an iPhone through a competition based on selecting a random number, after fulfilling the competition's conditions which include following the company's page and owning its product, considered permissible (halal) or forbidden (haram)?

There is no objection to benefiting from the prize, which is one of the promotional gifts given by merchants to consumers without compensation. This is in accordance with the statement of the Islamic Fiqh Academy: "A competition without compensation is a permissible and legitimate matter in every affair for which there is no text prohibiting it, and which does not result in the abandonment of an obligation or the commission of a forbidden act."
