Investing in a bank with a guarantee of the capital

Question:
He says: Honorable Shaykh, may Allah grant you success. There is an investment in the British bank, a land investment, where you pay a sum of money not less than seven thousand, and they guarantee only the capital, while the profits vary; they may be ten percent or more. The important thing is that they guarantee the capital. What is the ruling on investing with them?

Answer:
This is not permissible. This condition is not permissible. In a profit-sharing partnership, the safety of the capital is not a condition. Rather, if there is a profit, it is shared between them, and if there is a loss, the loss falls on the capital, on the owner of the money. As for the condition that they guarantee the capital, this is not permissible. There is no good in banks and their dealings; none of their dealings is free from what is forbidden and from conditions that are not Islamic and not valid.
