Surah Al-Imran, Verse 90

إِنَّ ٱلَّذِينَ كَفَرُواْ بَعۡدَ إِيمَٰنِهِمۡ ثُمَّ ٱزۡدَادُواْ كُفۡرࣰ ا لَّن تُقۡبَلَ تَوۡبَتُهُمۡ وَأُوْلَٰٓئِكَ هُمُ ٱلضَّآلُّونَ ﴿٩٠﴾

İnnellezıne keferu ba´de ımanihim sümmezdadu küfral len tukbele tevbetühüm* ve ülaike hümüd dallun

“But those who reject Faith after they accepted it, and then go on adding to their defiance of Faith,- never will their repentance be accepted; for they are those who have (of set purpose) gone astray”
