What is the ruling on taking a share of the profits in addition to the remaining amount, given that the livestock were not stolen but sold by the farmer?

It is permissible to entrust livestock to a man to care for them in exchange for half of their produce. If it is proven that the shepherd is lying in his claim that the livestock were stolen, then he is an aggressor and must guarantee them. If they are still alive, he must return them. Otherwise, he must return their value. If they have made a profit, he must return all of the profit.
