Too bad you joined this discussion at this point. So you may have to go back and read the posts by TLK and others who agreed that at present
Islamic banking is a dhoka bazi, fraud or at the minimum mis-labeled products.
And if you read the previous posts, you will clearly find why these products are a “clear lie” because they are nothing but the traditional banking products put under a green hijab.
And if you see this conclusion as “gibberish”, then may Allah swt help you.
