Surah At-Tawbah — Ayah 66 (9:66)
لَا تَعۡتَذِرُواْ قَدۡ كَفَرۡتُم بَعۡدَ إِيمَٰنِكُمۡۚ إِن نَّعۡفُ عَن طَآئِفَةٖ مِّنكُمۡ نُعَذِّبۡ طَآئِفَةَۢ بِأَنَّهُمۡ كَانُواْ مُجۡرِمِينَ ٦٦
English translation (Saheeh International)
Make no excuse; you have disbelieved [i.e., rejected faith] after your belief. If We pardon one faction of you - We will punish another faction because they were criminals.
Brief commentary
Do not present these false excuses, O hypocrites. You have exposed your disbelief, which was hidden, by making fun. If I were to pardon a group from among you, when they leave their hypocrisy and repent from it by sincerely repenting to Allah, I will punish another group from among you due to their remaining in hypocrisy and their failure to repent from it.
