What is the ruling on buying charging cards from wholesale stores instead of the company, then selling them to benefit from the price difference, knowing that this practice has been stopped and there is a fear of informing the administration about it?

If the questioner is entrusted with company money and uses it to buy cards, then sells them and profits from them, his action is impermissible. The profit resulting from this sale is a matter of scholarly disagreement. The preponderant fatwa (definition) is that the profit should be divided equally between the two parties. There is no obligation to inform the superiors of what was done; rather, it is sufficient to return the money by any means that does not result in harm or embarrassment. If the intention is other than this, the question must be clarified.
