Quran At-Tawbah 9:66
لَا تَعۡتَذِرُواْ قَدۡ كَفَرۡتُم بَعۡدَ إِيمَٰنِكُمۡۚ إِن نَّعۡفُ عَن طَآئِفَةٖ مِّنكُمۡ نُعَذِّبۡ طَآئِفَةَۢ بِأَنَّهُمۡ كَانُواْ مُجۡرِمِينَ ٦٦
Translation
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.
