His Two Brothers Send Him unlawful Provision

Question :

Being a student of knowledge, I have no source of income save what my two brothers send to me. One of them owns a restaurant in Germany, a restaurant, though, that sells alcohol and pork. Is it permissible for me to benefit from their wealth? What about the things I have already bought from money they had previously sent to me? What solution in general can you offer to me? Please consider it in your answer that I don't have anything to do with their business.

Answer:

You are not allowed to accept their money, and it is also your responsibility to advise them, stating very clearly that as Muslims they should stop selling what is unlawful, even if it means shutting down their establishment, changing to another line of work, or moving to another country and opening an Islamic restaurant; Allah Almighty says:
"Whosoever fears Allah and keeps his duty to Him, He will make a way for him to get out (from every difficulty)."

As for those gifts that you have received from them in the past, there is nothing to prevent you from keeping them, but don't accept any gifts from them in the future. Earn for yourself; Allâh Almighty provides for whomever He wills without limit.
