What is the reality of the existence of Islamic banks and how to deal with them in a Sharia-compliant manner? What are the Islamic banks in which a Muslim can invest, and can their electronic links be provided in Arabic?

A bank's designation as Islamic depends on the sincerity of its operators in applying the rulings of Sharia, their piety, and their level of knowledge. Differences among banks arise based on these factors. It is absolutely permissible to deal with banks that adhere to Sharia controls. However, it is not permissible to deal with lenient banks except for operations that one is certain are conducted in accordance with Sharia. This can be verified through the bank's Sharia committee and the trustworthy scholars of the country.
