Does Fatwa No. 123806, which permits money earned from working with pirated software, contradict the fatwas that prohibit profit gained from stolen money?

There is no contradiction between the fatwa concerning profit gained from pirated software and the fatwas that addressed the issue of profit gained from stolen money. Using pirated software is an infringement upon the rights of its owners, and the user is obligated to pay for the benefits he has foregone. However, the fruit of his effort belongs to him. If he were to infringe upon the core program itself and sell it, he would be like a thief.

The reason for the disagreement regarding profit from stolen or usurped money goes back to certain hadiths. Some of them imply that the aggressor has no right, such as the hadith: "There is no right for a wrongdoer's exertion." Others imply that the profit belongs to the guarantor, such as the hadith: "Profit follows liability," or that the profit is to be divided between them.
