What is the ruling on investing in a company that offers investment packages with daily profits and a fixed percentage for a specified period, and requires liking and sharing advertising posts, and adopts a multi-level sponsorship system where the sponsor benefits from percentages of the investments of those who register through them?

It is impermissible to invest in a company that makes profit a percentage of the capital, such as giving you 1.41% of your capital daily, because that makes the profit a known amount of money, which invalidates the partnership. Instead, the client's share must be a common percentage of the profits, not of the capital. If the guarantee of capital is combined with the profit being a percentage of it, then this is a prohibited usurious loan.

Furthermore, network marketing that involves a subscription fee is a prohibited form of gambling, due to the possibility of the client losing the paid amount if they are unable to bring in other customers.
