Is Eating Niyaz, Or Earning Of A Sin Equates To Sin Itself?
Committing shirk is one thing, and participating in eating is another sin of disobeying God, not shirk, but it can be kufr.
@Irfan76 so sir it would be same as like eating pork while knowing God has forbidden it, or stealing something deliberately.. They all would be kufr in similar lines, am I right sir?
