He used to raise the price for customers and keep the increase for himself; how does he clear his conscience regarding the money?

Question:
May Allah reward you with good, and may He do you good. We move on to another topic and another letter from Riyadh, from a listener who indicated his name with the letters Ayn, Ayn, Ayn. He says: I work in one of the commercial establishments, and in the past I used to raise the price of goods for customers above their original value, keep the increase for myself, and pay the owner of the establishment the original price. But now I have repented to Allah. I want to clear my conscience. What should I do? Please guide us. May Allah reward you with good.

Answer:
You have erred in this action. You have wronged people by deceiving them and raising the prices of goods against them, and you have also betrayed the owner of the establishment whose goods you exploited in this deception. You are sinful in this, wronging people, and consuming their money unlawfully. If you know these people whom you wronged and took the increase from, then you must return to them what you took from them, or ask them for forgiveness. If you do not know them, then you give in charity the amount you took, on the behalf of these people, with the intention that the reward belongs to them and you clear your conscience of these rights. The reality is that this matter is forbidden, consuming people's money unlawfully, and betraying the trust placed in you. You must repent to Allah the Exalted and Majestic, and you must return the rights to their owners if you are able, or give them in charity with the intention that the reward belongs to their unknown owners. Yes.
