There are several opinions on whether Islamic banking is truly Halal or not? There is a lot of difference in opinion on the financial instruments as summarised and detailed between the muftis as well when it comes to Islamic finance but you can always find a safe way in sha ALLAH.
For those who declare Islamic Banking Halal
Those in favor of this opinion rate Islamic Banking typically a different model of banking compared to Conventional Banking. The main point is that Islamic Banking and Conventional banking are two different things, one should not confuse the interest earnings by the bank with the profits they earn through their trade activities. Hence, to them it is Halal.
Islamic banking is purely halal banking and certified by mufityan deen so no questions about their authenticity and halaal
