Gambling companies sometimes send free offers (to allure) to participate in the game and get a chance to win. Absolutely no money is required for this advertisement offer. From Islamic point of view, is there any arm in participating in such offers?
There are two aspects to your query: a) Is it gambling or not? b) Is it
permissible to participate in such a game?
In principle, that is not gambling. However, participating in the game, that
depends on the nature of the game. If there is anything un-Islamic in the
game, it will be prohibited even though it may not be gambling.
and Allah Ta’ala Knows Best
