Excess payments received from customers

If it is found that the excess amount does not belong to the business and in fact, it belongs to the customers, then the customers will have to be located and the excess amount will have to be returned to them. If this is not possible, then the excess amount cannot be used or kept and will have to be dispensed of in charity.

It is not permissible to use the excess money without the permission and consent of the customers.

And Allah Ta’ala Knows Best
