Surely, those who believe, then disbelieve, then believe, then disbelieve, then plunge deeper into disbelief, God will not forgive them, nor will He guide them in any way.
إِنَّ الَّذينَ ءامَنوا ثُمَّ كَفَروا ثُمَّ ءامَنوا ثُمَّ كَفَروا ثُمَّ ازدادوا كُفرًا لَم يَكُنِ اللَّهُ لِيَغفِرَ لَهُم وَلا لِيَهدِيَهُم سَبيلًا
innal lazeena aamanoo summa kafaroo summa aamanoo summa kafaroo summaz daado kufral lam yakunil laahu liyaghfira lahum wa laa liyahdiyahum sabeelaa
