Sura 3 Ali 'Imran (Family of Imran), ayat 90

1. إِنَّ الَّذِينَ كَفَرُوا بَعْدَ إِيمَانِهِمْ ثُمَّ ازْدَادُوا كُفْرًا لَنْ تُقْبَلَ تَوْبَتُهُمْ وَأُولَٰئِكَ هُمُ الضَّالُّونَ

   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.

   3:90
