Quran 16:106 An-Nahl, ayah 106 of 128

مَن كَفَرَ بِٱللَّهِ مِنۢ بَعْدِ إِيمَـٰنِهِۦٓ إِلَّا مَنْ أُكْرِهَ وَقَلْبُهُۥ مُطْمَئِنٌّۢ بِٱلْإِيمَـٰنِ وَلَـٰكِن مَّن شَرَحَ بِٱلْكُفْرِ صَدْرًا فَعَلَيْهِمْ غَضَبٌ مِّنَ ٱللَّهِ وَلَهُمْ عَذَابٌ عَظِيمٌ ۝١٠٦

16:106 Whoso disbelieveth in Allah after his belief - save him who is forced thereto and whose heart is still content with the Faith - but whoso findeth ease in disbelief: On them is wrath from Allah. Theirs will be an awful doom.
