What is the ruling on the money taken by a manager and partner in a company, which resulted from commissions he received from the entity from which he used to purchase spare parts for the company, and which he used to buy a villa and a farm before his death? Is this money lawful, and how should his children act if it is not lawful, in order to free their father from this sin?

The managing partner, who is entrusted with purchasing spare parts, acts as an agent for his partners. It is not permissible for him to take a commission from spare parts companies without their permission. If he dies having taken money unjustly and built a house and a farm with it, his heirs must remove the amount of unlawful money from his estate. The money should be returned to its owner if found; otherwise, it should be spent for the benefit of Muslims. If this is done, then there is no blame on them for benefiting from the house and the farm. If the estate is insufficient, they must sell the house and the farm to restore the right.
