Oh Muslims my advise to you is that the way you put your best of brain (kids with good brain) into uloom and knowledge of dunya likes of; Medicine and they become best of doctors and help the nation and world wide in issues of health and you put your best of brain (kids) into Engineering and they make the world highest of sky scrappers and huge bridges and bring the understanding how scientific theories work in electric and mechanics and the chemistry of different things (study of matters and its properties) and the best brain in Architecture and designing and Education from early childhood till the masters and university level to get the best of knowledge and the best of brain to serve your nation.
Likewise my advise is that put your best of brain (intelligent generation) into deen as well. So the best mind and best brain can understand and comprehend the in depth knowledge of Qur'an and sunnah and methodology of previous pious predecessors called Salaf-as-saalih, to give the fatwah and opinion based on sharai adillah (legislated opinion based on Qur'an and sunnah and ijmaah).
Do not put the dumb minded kids into deen, because it may destroy the upcoming generation by giving the opinion and legislation may not have ANYTHING to do with Qur'an and Sunnah.
May Allaah azza wa jallah bring this understanding into all the Muslims around the globe, Allahumma ameen.
