Yunus 10:100

Wama kana linafsin an tu/minailla bi-ithni Allahi wayajAAalu arrijsaAAala allatheena la yaAAqiloon

And it is not for a soul [i.e., anyone] to believe except by permission of Allāh, and He will place defilement upon those who will not use reason.

It is not (possible) for any one that he believes except with the will of Allah. And He makes filth settle on those who do not understand.
