My father brought some goods into the house

Q 2: A Muslim had a business contract with some European companies. He used to sell them goods for a fixed price but he tricked them with the help of the company representative who was one of them. This Muslim would bring ten barrels of oil and the representative - who came up with the idea - would record them as twelve, and they would split the profits. What is the ruling on this money? If it is Haram (prohibited), what should this Muslim do after this unlawfully gained money has mixed with his lawfully gained money? He has already gotten married and bought a car.

A: If the matter is as you have mentioned, this Muslim should give back all the unlawful money he has taken to the company. Yet if it is hard for him to return the money, he can give it in charity, (Part No. 15; Page No. 344) seek Allah's Forgiveness and perform Tawbah (repentance to Allah). He should regret what he has done and resolve not to go back to it. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
