I operate a platform for all restaurants to sell their food online but there are restaurants who also sell pork and alcohol. Will their sales on my website make my income Haram?
Muslim is not allowed to sell or take part in marketing or selling alcohol or pork. You should refrain putting such unlawful items on your website or platform. If you sell such Haraam items,bayou will be committing a sinful act, and every income from such work is Haraam as well.
You should keep your platform and business activities clean and pure from any Haraam business.
Wassalam.
