4:137
إِنَّ ٱلَّذِینَ ءَامَنُوا۟ ثُمَّ كَفَرُوا۟ ثُمَّ ءَامَنُوا۟ ثُمَّ كَفَرُوا۟ ثُمَّ ٱزۡدَادُوا۟ كُفۡرࣰا لَّمۡ یَكُنِ ٱللَّهُ لِیَغۡفِرَ لَهُمۡ وَلَا لِیَهۡدِیَهُمۡ سَبِیلَۢا
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.
— Mohammed Marmaduke William Pickthall
