(Annisa) 4 : 137
إِنَّ الَّذِينَ آمَنُوا ثُمَّ كَفَرُوا ثُمَّ آمَنُوا ثُمَّ كَفَرُوا ثُمَّ ازْدَادُوا كُفْرًا لَمْ يَكُنِ اللَّهُ لِيَغْفِرَ لَهُمْ وَلَا لِيَهْدِيَهُمْ سَبِيلًا
Indeed, for those who believed, then disbelieved and then believed, and then disbelieved, then increased in disbelief, Lord Allah will be never forgiving them nor will He be guiding them to the Straightpath.
