اٰل عمران — Ali 'Imran Ayat 90
اِنَّ الَّذِيْنَ كَفَرُوْا بَعْدَ اِيْمَانِهِمْ ثُمَّ ازْدَادُوْا كُفْرًا لَّنْ تُقْبَلَ تَوْبَتُهُمْ ۚ وَاُولٰۤىِٕكَ هُمُ الضَّاۤلُّوْنَ
Innal-lażīna kafarū ba‘da īmānihim ṡummazdādū kufral lan tuqbala taubatuhum, wa ulā'ika humuḍ-ḍāllūn(a).
"Indeed, those who reject the message after their belief and then increase in disbelief - never will their [claimed] repentance be accepted, and they are the ones astray."
