Allah SWT says: وَمَا كَانَ لِنَفْسٍ أَنْ تُؤْمِنَ إِلَّا بِإِذْنِ اللَّهِ ۚ وَيَجْعَلُ الرِّجْسَ عَلَى الَّذِينَ لَا يَعْقِلُونَ "And it is not for a soul to believe except by permission of Allah, and He will place defilement upon those who will not use reason." (QS. Yunus: Verse 100) * Via the Beautiful Qur'an https://goo.gl/QLwc8B
