What is the ruling on working for an Islamic Murabaha company that performs two functions, where the accountant rounds up checks to the nearest Dinar at the manager's request, and there is doubt regarding the goods sold from the warehouses?

It is not permissible to sell a commodity to the bank and then for the customer to buy it from the bank under the name of another company, as this involves a suspicion of 'inah (a type of usurious transaction) and circumvention of usury. It is also not permissible to round off amounts in checks because it is a condition in murabaha and tawarruq transactions that the price be known. Furthermore, it is not permissible for the company to complete a sale contract on a commodity before owning it, as this falls under selling what one does not own, which is prohibited by Sharia. The questioner must leave work in this company if he cannot avoid the forbidden and assisting in it.
