Sheikh.I am working on a revenue sharing site.Is this halal? I buy adpacks(shares) where I get visitors to my websites. The more adpacks(shares) I buy the more visitors I get thus more profit I get when my share is sold.I have to login to that site everyday and click 10 ads that’s all I do to make profit.
