What is the ruling of Islamic law on entering the global stock market through a foreign bank in Dubai, where a one-year linked bank deposit letter for an amount of 10 million dollars is required, with the depositor receiving monthly profits of 50% of the principal amount, the bank 40%, and the broker 10%?

The type of bank (usurious or non-usurious), the nature and terms of the contracts concluded, and the nature of its dealings with the global stock market were not mentioned, nor whether it adheres to Sharia controls in all of that. Therefore, the mentioned transaction cannot be ruled upon. However, most foreign banks deal in usury and unlawful matters, so it is advisable to avoid this transaction.
