What is the Sharia ruling on subscribing to Al-Bilad Islamic Bank, and selling the shares after their price rises in a short period?

It is not possible to rule on the permissibility of subscribing to shares in the mentioned bank, due to a lack of knowledge regarding the nature of its transactions and the extent of their compliance with Sharia guidelines. To issue a ruling, the nature of the bank's transactions must be clarified. The enquirer can seek clarification from scholars in their country, especially from the bank's Sharia committee if it is trustworthy. If it is confirmed that the bank is Islamic and compliant with Sharia, then there is no harm in subscribing to its shares.
