Quran 58:8 from Surah Al-Mujaadila on Divine Marvels.
أَلَمۡ تَرَ إِلَى ٱلَّذِينَ نُهُواْ عَنِ ٱلنَّجۡوَىٰ ثُمَّ يَعُودُونَ لِمَا نُهُواْ عَنۡهُ وَيَتَنَٰجَوۡنَ بِٱلۡإِثۡمِ وَٱلۡعُدۡوَٰنِ وَمَعۡصِيَتِ ٱلرَّسُولِۖ وَإِذَا جَآءُوكَ حَيَّوۡكَ بِمَا لَمۡ يُحَيِّكَ بِهِ ٱللَّهُ وَيَقُولُونَ فِيٓ أَنفُسِهِمۡ لَوۡلَا يُعَذِّبُنَا ٱللَّهُ بِمَا نَقُولُۚ حَسۡبُهُمۡ جَهَنَّمُ يَصۡلَوۡنَهَاۖ فَبِئۡسَ ٱلۡمَصِيرُ
English translation: Do not you see [to] those who were forbidden from secret counsels then they return to what they were forbidden from [it] and they hold secret counsels for sin and aggression and disobedience (to) the Messenger And when they come to you they greet you with what not greets you therewith Allah and they say among themselves Why (does) not Allah punish us Allah punish us for what we say Sufficient (for) them (is) Hell they will burn in it and worst is the destination
