Verse 66

لَا تَعْتَذِرُوا۟ قَدْ كَفَرْتُم بَعْدَ إِيمَـٰنِكُمْ إِن نَّعْفُ عَن طَآئِفَةٍ مِّنكُمْ نُعَذِّبْ طَآئِفَةًۢ بِأَنَّهُمْ كَانُوا۟ مُجْرِمِينَ

Do not make excuses for disbelieving after attaining faith. If We pardon a group of you, We will punish another group due to their proven wickedness.
