What is the ruling on buying Al-Rajhi shares and then selling them to a third party with payment made in installments with an increase?

If you buy shares in installments and sell them for cash, this transaction is known as Tawarruq. It is a condition for the permissibility of dealing in shares that the company's field of work be permissible, and that it does not invest any part of the shareholders' money in usurious banks. Regarding Al-Rajhi shares, the scholars of the Kingdom should be asked about them.
