ذَٰلِكَ بِأَنَّهُمْ ءَامَنُوا۟ ثُمَّ كَفَرُوا۟ فَطُبِعَ عَلَىٰ قُلُوبِهِمْ فَهُمْ لَا يَفْقَهُونَ
How to read it
Dhālika bi'annahum' 'āmanū thumma kafarū faṭubiʻa ʻalā qulūbihim' fahum' lā yaf'qahūna
That is because they believed, then they rejected Faith: So a seal was set on their hearts: therefore they understand not.
Translation: Abdullah Yusuf Ali
