Rejection of insincerity

يَعْتَذِرُونَ إِلَيْكُمْ إِذَا رَجَعْتُمْ إِلَيْهِمْ ۚ قُل لَّا تَعْتَذِرُوا۟ لَن نُّؤْمِنَ لَكُمْ قَدْ نَبَّأَنَا ٱللَّهُ مِنْ أَخْبَارِكُمْ ۚ وَسَيَرَى ٱللَّهُ عَمَلَكُمْ وَرَسُولُهُۥ ثُمَّ تُرَدُّونَ إِلَىٰ عَـٰلِمِ ٱلْغَيْبِ وَٱلشَّهَـٰدَةِ فَيُنَبِّئُكُم بِمَا كُنتُمْ تَعْمَلُونَ

They will make excuses to you when you have returned to them. Say, "Make no excuse - never will we believe you. Allāh has already informed us of your news [i.e., affair]. And Allāh will observe your deeds, and [so will] His Messenger; then you will be taken back to the Knower of the unseen and the witnessed, and He will inform you of what you used to do."
