لماذا خلق الله سكان دول الغرب أجمل من العرب، ولماذا هم أفضل منا في الاختراعات والتطور؟

The definitive answer to the issue of divine decree (Qadar) and the actions of Allah Almighty is submission to the fact that Allah does what He wills and differentiates among His servants, and that He is not questioned about what He does. This is coupled with the belief that He is All-Wise, doing nothing إلا وله فيه أتم الحكمة (except that it contains the most perfect wisdom), but that His servants cannot comprehend His wisdom. As for your mention that those individuals are more beautiful in creation, that is a subjective and relative matter of taste. Regarding the backwardness of Muslims in science and technology, the reasons for this have been detailed in previous fatwas.
