What is the ruling on investing in a company that sells ready-made clothes and cosmetics, where products are purchased through it, and the investor has the right to market them himself or through the company under a contract that stipulates the investor's receipt of double the amount after six months, without guaranteeing profit in case of disasters, as explained in the attached contract?

If the company's work involves marketing permissible goods, then there is no objection to investing in it and appointing it as an agent for selling after the transaction is completed. It is permissible to set a price for the commodity, and anything in excess of that price belongs to the company. They are your agents in selling, but it is not permissible to stipulate their guarantee of obtaining the specified price, because an agent does not guarantee the principal capital or the profit. He is a trustee who does not guarantee what is damaged in his possession without negligence.
