Qur'ān 9:66 · At-Tawbah (التوبة)

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

Make no excuse; you have disbelieved after your belief. If We pardon one faction of you - We will punish another faction because they were criminals.
