Surah Yunus, Verse 100

وَمَا كَانَ لِنَفۡسٍ أَن تُؤۡمِنَ إِلَّا بِإِذۡنِ ٱللَّهِۚ وَيَجۡعَلُ ٱلرِّجۡسَ عَلَى ٱلَّذِينَ لَا يَعۡقِلُونَ١٠٠

wamā kāna linafsin an tu'mina illā bi-idh'ni l-lahi wayajʿalu l-rij'sa ʿalā alladhīna lā yaʿqilūna

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.
