What are the names of the reliable Islamic banks in Qatar that can be dealt with to avoid usury (riba), and what are the permissible transactions offered by them, such as Visa, car loans, and qard hassan (benevolent loans), and what are their conditions?

If it is possible to transfer the salary from a Riba-based bank to an Islamic bank, then this is obligatory due to the impermissibility of dealing with Riba-based banks. Permissible transactions in Islamic banks include Murabaha and Mudarabah. The Visa card issued by Islamic banks is permissible if it is free from the condition of increasing the amount in case of delay and Riba-based interest. A Qard Hasan (benevolent loan), which is repaid without an increase, is permissible, but there is no known bank that offers it.
