Surah An-Nisaإِنَّ ٱلَّذِينَ ءَامَنُواْ ثُمَّ كَفَرُواْ ثُمَّ ءَامَنُواْ ثُمَّ كَفَرُواْ ثُمَّ ٱزۡدَادُواْ كُفۡرٗا لَّمۡ يَكُنِ ٱللَّهُ لِيَغۡفِرَ لَهُمۡ وَلَا لِيَهۡدِيَهُمۡ سَبِيلَۢا
Those who believe, and then disbelieve, and then believe, and then disbelieve, and then increase in unbelief-God is not likely to forgive them, neither to guide them on any way
