Sura al-Tawbah 9:66

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

lā taʿtadhirū qad kafartum baʿda īmānikum in nnaʿfu ʿan ṭāʾifatin minkum nuʿadhdhib ṭāʾifatan bi-annahum kānū mujrimīna

Make ye no excuses: ye have rejected Faith after ye had accepted it. If We pardon some of you, We will punish others amongst you, for that they are in sin.
