I work for a private company and my friend works for another. We have agreed on working together in different fields relying on our expertise and personal acquaintances in the labor market. In fact, my friend holds an important position in the company where he works, and it has lots of enterprises which he steers in the direction that he finds fit, so he started referring micro-enterprises to our company, and I started executing many of them for their market price, or less, but with maintaining the required standards, and the profit is shared by both of us. However, the owner of the company doesn`t know that I`m the partner of the manager in his company. What is the ruling of Sharia on this, and the money that we have earned so far?
