Is it Islamically permissible for an agreement to stipulate giving the financier 10% of the profit from only one type of product (mats), with the financier bearing the same percentage of loss if it occurs, knowing that the capital may be used for products other than this one, and that the principal capital of the entrepreneur is $80,000, while the partner's capital is $25,000, and is it a condition that he be given a share of the profit from all types of products for the transaction to be permissible?

It is not permissible to invest the money in a hasir (mat) and other ventures, and then give its owner profit only from the hasir, because the condition and the mudarabah (commenda partnership) are invalid in this case. This is because it is possible that profit is generated only from that specific item and not from others, thus one of you would exclusively receive the profit, which contradicts the nature of a partnership.

However, if you will invest this money solely in the hasir, then this is permissible, and whatever profit you agree upon is permissible, provided that the capital owner's share of the loss does not exceed his capital.
