Consuming food with stolen money

Q 3: There is a university student whose father is a thief who steals the money of Muslims in Saudi Arabia. Is it permissible for him to continue his studies and consume unlawful money when he visits him?

A: It is Haram (prohibited) to consume unlawful money or use it in one's (Part No. 22; Page No. 339) studies or for other purposes, according to the relevant general proofs, such as the saying of the Prophet (peace be upon him), Verily your blood, your property and your honors are sacred and inviolable. However, if the stolen money is mixed with other lawful money, there is controversy over the permissibility of making use of it.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
