The Islamic family law has in the past advocated for passing on of family wealth from one generation to another. This according to Prof. Timur Kuran of Duke University limited the amassing of wealth and therefore dragging down development.
Many have attempted to link economics and religious doctrines and have met with exceptions and better explanations. During the Ottoman and also some Post- Ottoman era and places, both Christians and Jews did quite well businesswise. This does not imply that the Muslim majority were backward economically.
