Islam make it compulsory for Muslims to seek religious as well as secular education so i dont know why a Muslim who is good in fiqh(slamic jurisprudence) cannot be good in maths and physics...
Really??
Let me give you an example......in order to be a Biologist you need to understand and accept one of its basic theories: the theory of evolution, which Islam condemns......
Islam teaches that humans were directly created by the Almighty, they didn't evolve.....
Now tell me, how can one understand and progress in modern bio-science without accepting evolution.....and thus going against Islamic teachings
