Purchasing something from Haram Rizq

Question 004: I am a teenager that knows that my father is earning Haram Rizq (money). If something is purchased from that money does it also become haram?

Answer 004: If you are absolutely sure he is earning haram rizq you are not allowed to buy anything from that money. Otherwise, if you are not sure, there would be no problem to use it.

Therefore, buying anything with money earned in a fashion that is haram rizq, makes the thing itself haram.

Note: forbidding others from haram acts, or enjoining them to do their wajib ones, is wajib (obligatory) upon us, because it falls under the category of amr bil ma’ruf wa nahy anil munkar, and this applies to everyone. Thus, carrying this religious duty is also wajib, given that all the conditions are met and that it certainly applies.
