Does man choose his own destiny or has God predetermined his destiny?
This becomes clearer with a simple example:
Suppose you enter a pharmacy and the pharmacy doctor who is there tells you that you are free to choose any medicine you want (strengthening medicine or sleeping medicine or…), at the same time, you can see the result and effect of the medicine. See a selection in a previously written book. A wise doctor is someone who has told you the positive or negative effect of the medicine before taking it.
“God will not change the destiny of any nation unless they change what is in themselves”.
(Surah Mubarakah Raad verse 11)
