Is it permissible for the owner of an investment company to pay investors profits exceeding what is due, and to waive a large portion of his own profit or pay from his personal funds, with the aim of maintaining the company's continuity and preventing them from withdrawing their money?

The mentioned transaction is a Mudarabah (profit-sharing partnership). For it to be permissible, it must adhere to its Sharia-compliant conditions, which are: 1. The agent (Mudarib) should not guarantee the capital, except in cases of negligence or transgression. 2. The share of each party in the profit must be a common percentage (such as one-third or one-fourth), not a fixed amount or a percentage added to the capital. 3. In a joint Mudarabah, the capitals of the partners must be distinguished, and the owner of the capital must be asked for permission before mixing his money with that of others.

If both parties adhere to these conditions, and the agent voluntarily gives some of his profits to the owner of the capital without it being stipulated, then there is no objection.
