النساۤء — An-Nisa' Ayat 137
اِنَّ الَّذِيْنَ اٰمَنُوْا ثُمَّ كَفَرُوْا ثُمَّ اٰمَنُوْا ثُمَّ كَفَرُوْا ثُمَّ ازْدَادُوْا كُفْرًا لَّمْ يَكُنِ اللّٰهُ لِيَغْفِرَ لَهُمْ وَلَا لِيَهْدِيَهُمْ سَبِيْلًاۗ
Innal-lażīna āmanū ṡumma kafarū ṡumma āmanū ṡumma kafarū ṡummazdādū kufral lam yakunillāhu liyagfira lahum wa lā liyahdiyahum sabīlā(n).
"Indeed, those who have believed then disbelieved, then believed, then disbelieved, and then increased in disbelief - never will Allah forgive them, nor will He guide them to a way."
