63:3
ذَٰلِكَ بِأَنَّهُمْ ءَامَنُوا۟ ثُمَّ كَفَرُوا۟ فَطُبِعَ عَلَىٰ قُلُوبِهِمْ فَهُمْ لَا يَفْقَهُونَ
Zaalika bi annahum aamanoo summa kafaroo fatubi'a 'alaa quloobihim fahum laa yafqahoon
That is because they believed, then they rejected Faith: So a seal was set on their hearts: therefore they understand not.
