Qur'an 2:256

لَآ إِكْرَاهَ فِى ٱلدِّينِ ۖ قَد تَّبَيَّنَ ٱلرُّشْدُ مِنَ ٱلْغَىِّ ۚ فَمَن يَكْفُرْ بِٱلطَّـٰغُوتِ وَيُؤْمِنۢ بِٱللَّهِ فَقَدِ ٱسْتَمْسَكَ بِٱلْعُرْوَةِ ٱلْوُثْقَىٰ لَا ٱنفِصَامَ لَهَا ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌ

“There shall be no compulsion in [acceptance of] the religion. The right course has become distinct from the wrong. So whoever disbelieves in ṭāghūt and believes in Allāh has grasped the most trustworthy handhold with no break in it. And Allāh is Hearing and Knowing.”
