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

“Do not offer [empty] excuses! You have indeed denied the truth after [having professed] your belief [in it] - Though We may efface the sin of some of you, We shall chastise others - seeing that they were lost in sin.”

Make no excuses for that. You have disbelieved after believing that is your disbelief has become manifest even as you have manifested belief. If We forgive read passive yu‘fa ‘it is forgiven’ or active first person plural na‘fu ‘We forgive’ a party of you because of its sincerity and its repentance as in the case of Jahsh b. Humayyir We will chastise read either passive tu‘adhdhab ‘it shall be chastised’ or nu‘adhdhib another party because they were sinners’ persisting in hypocrisy and mockery.
