Ruling on depositing money in a company in exchange for a percentage of the profits

Question:
I deposited some money in a gold company, for the purpose of buying and selling this money, in exchange for 1% of the profit for the company, knowing that the company does not guarantee the profit, nor does it cover the loss?

Answer:
If you contract with the company to work with your gold, or your silver, or your paper currency, working with it and taking 1% of the profit, with the rest belonging to you, there is no harm. 1% means one-tenth of a tenth, there is no harm.
If the company engages in buying and selling, and a profit is realized, and you give it 1000, and a hundred is realized from the thousand, it takes one riyal from the hundred, there is no harm.
However, if it takes the hundred from the capital, or guarantees you a riyal in the hundred, that is not permissible. But if it is from the profit, working on the basis that the profit is 1% or 5% or 10%, the point is that it is a known, shared amount, then there is no harm.
