It's a great read, congratulations!
I understand what you mean when you say "Islam religion(not Muslim people)" but I think it is impossible to disintegrate any religion from the society and treat it as an abstract object. 1. Women rights. 2. I grew up in Turkey and in Turkey there is a mandatory "Religious Culture and Morality" course throughout the elementary and high school education. Apart from my immediate family every relative I have is a practicing Muslim. So I got the information through education and experience. 3. I can't think of any question about Islam particularly but on religion in general I would probably ask "how is your definition of God different than the definition of a self aware/conscious universe?". Or similarly "how do you feel about your God, still having done everything you think it did, not being self aware/conscious?".
It is interesting that the wealth-happiness correlation is flat after a certain income level for the experiencing self but not for the remembering self. What came to my mind is the negativity bias since it predicts the opposite result. I am not sure but according to the negativity bias one would expect that the experience of not feeling happy would be emphasised by the remembering self. At first these two seem to contradict but it could also mean that "not feeling happy" is not necessarily same with "feeling unhappy".
