مَن كَفَرَ بِٱللَّهِ مِنۢ بَعْدِ إِيمَـٰنِهِۦٓ إِلَّا مَنْ أُكْرِهَ وَقَلْبُهُۥ مُطْمَئِنٌّۢ بِٱلْإِيمَـٰنِ وَلَـٰكِن مَّن شَرَحَ بِٱلْكُفْرِ صَدْرًا فَعَلَيْهِمْ غَضَبٌ مِّنَ ٱللَّهِ وَلَهُمْ عَذَابٌ عَظِيمٌ
man kafara billaahi mim ba'di eemaanihee illaa man ukriha wa qalbuhoo mutmma'innum bil eemaani wa laakim man sharaha bilkufri sadran fa'alaihim ghadabum minal laahi wa lahum 'azaabun 'azeem
With the exception of those who are forced to say they do not believe, although their hearts remain firm in faith, those who reject God after believing in Him and open their hearts to disbelief will have the wrath of God upon them and a grievous punishment awaiting them.
Whoever denies God after having believed — except one who is coerced while his heart remains at peace in faith — but whoever opens his heart to denial, upon them is wrath from God, and theirs is a tremendous punishment.
