Qur'an 9:66 · At-Tawba

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

(66) 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.
