Quran 9:66 At-Tawbah, ayah 66 of 129

لَا تَعْتَذِرُوا۟ قَدْ كَفَرْتُم بَعْدَ إِيمَـٰنِكُمْ ۚ إِن نَّعْفُ عَن طَآئِفَةٍ مِّنكُمْ نُعَذِّبْ طَآئِفَةًۢ بِأَنَّهُمْ كَانُوا۟ مُجْرِمِينَ ۝٦٦

9:66 Make no excuse. Ye have disbelieved after your (confession of) belief. If We forgive a party of you, a party of you We shall punish because they have been guilty.
