An-Nahl 16:106

مَن كَفَرَ بِٱللَّهِ مِنۢ بَعۡدِ إِيمَٰنِهِۦٓ إِلَّا مَنۡ أُكۡرِهَ وَقَلۡبُهُۥ مُطۡمَئِنُّۢ بِٱلۡإِيمَٰنِ وَلَٰكِن مَّن شَرَحَ بِٱلۡكُفۡرِ صَدۡرٗا فَعَلَيۡهِمۡ غَضَبٞ مِّنَ ٱللَّهِ وَلَهُمۡ عَذَابٌ عَظِيمٞ 106

Whoever disbelieves in Allah after his belief... except for one who is forced [to renounce his religion] while his heart is secure in faith. But those who [willingly] open their breasts to disbelief, upon them is wrath from Allah, and for them is a great punishment
