إِنَّ الَّذِينَ آمَنُواْ ثُمَّ كَفَرُواْ ثُمَّ آمَنُواْ ثُمَّ كَفَرُواْ ثُمَّ ازْدَادُواْ كُفْرًا لَّمْ يَكُنِ اللّهُ لِيَغْفِرَ لَهُمْ وَلاَ لِيَهْدِيَهُمْ سَبِيلاً
[4:137]
Surely (as for) those who believe then disbelieve, again believe and again disbelieve, then increase in disbelief, Allah will not forgive them nor guide them in the (right) path.
Those who believe, then reject faith, then believe (again) and (again) reject faith, and go on increasing in unbelief,- Allah will not forgive them nor guide them nor guide them on the way.
Lo! those who believe, then disbelieve and then (again) believe, then disbelieve, and then increase in disbelief, Allah will never pardon them, nor will He guide them unto a way.
