لاَ تَعْتَذِرُواْ قَدْ كَفَرْتُم بَعْدَ إِيمَانِكُمْ إِن نَّعْفُ عَن طَآئِفَةٍ مِّنكُمْ نُعَذِّبْ طَآئِفَةً بِأَنَّهُمْ كَانُواْ مُجْرِمِينَ
﴿٦٦﴾
سورة التوبة
(9/66) Do not invent excuses. You have indeed disbelieved after your belief. If We pardon a party of you; We will torment (another) party because they are guilty.
Surah At-Tawbah
