@lamea: Yes I agree with your father's experience. If you go out do some research you will find the reality of this fake Islamic banking. In reality this is the same interest based banking behind the scene. The west just opened a small window in that same crap banking and says, "Hey this is Islamic banking following the rules of Islam". They are making the Muslims fools by saying that and Muslims are becoming fool because they don't know their own Islamic economic model. If you don't believe me, go and do some research related to it. First go and study what Islam says about it. What is Islamic economic model? How this interest based banking started and what mess it's creating in the world today.
