What is the ruling on participating in bank shares, such as the Emirates Bank in Saudi Arabia? Is it permissible or forbidden?

We cannot issue a ruling on the aforementioned bank due to our ignorance of the nature of its transactions and its adherence to Sharia regulations. A ruling on something remains a corollary of its conception. There are regulations and conditions for buying and selling shares; if these are met, it is permissible, otherwise, it is not.
