Concept Of Helping One In Sin And Its Applications (Tawun Alal Ithm)
This is obvious in your knowledge it is for something bad so you cannot help him. but when you help someone in ordinary matters and he used that help for bad then it is not your responsibility.
@Irfan76 but sir wasn’t there a possibility known to my knowledge in the Hindu example as well?
When you believe something haram you have to avoid it for your own sake first, even if the matter is not of usurping others rights.
