Have you not considered those who were forbidden from private conversation, then (58:8)

﴿أَلَمْ تَرَ إِلَى الَّذِينَ نُهُوا عَنِ النَّجْوَىٰ ثُمَّ يَعُودُونَ لِمَا نُهُوا عَنْهُ وَيَتَنَاجَوْنَ بِالْإِثْمِ وَالْعُدْوَانِ وَمَعْصِيَتِ الرَّسُولِ وَإِذَا جَاءُوكَ حَيَّوْكَ بِمَا لَمْ يُحَيِّكَ بِهِ اللَّهُ وَيَقُولُونَ فِي أَنفُسِهِمْ لَوْلَا يُعَذِّبُنَا اللَّهُ بِمَا نَقُولُ ۚ حَسْبُهُمْ جَهَنَّمُ يَصْلَوْنَهَا ۖ فَبِئْسَ الْمَصِيرُ﴾
[ المجادلة: 8]

58:8 Have you not considered those who were forbidden from private conversation, then they return to that which they were forbidden and converse among themselves about sin and aggression and disobedience to the Messenger? And when they come to you, they greet you with that [word] by which Allah does not greet you and say among themselves, "Why does Allah not punish us for what we say?" Sufficient for them is Hell, which they will [enter to] burn, and wretched is the destination.

O Messenger! Do you not see the Jews who used to secretly whisper when they would see a believer, then Allah prohibited them from such whispering, but they would return to committing exactly that which Allah prohibited them from: secretly discussing sin among themselves i.
e.
backbiting the believers, inciting people against them, and disobedience to the Messenger.
O Messenger! When they come to they greet you with a greeting Allah has not taught you to greet with, i.
e.
by saying: ‘As-sāmu ‘alayk’ meaning ‘death be upon you’, and they say, rejecting the Prophet ( peace be upon him ): “Why does Allah not punish us for what we say? Because if he was truthful in his claim that he is a Prophet, Allah would have punished us for what we say about him!” Hell is enough of a punishment for them for what they say; they will definitely suffer its heat.
What an evil outcome they will face!

Have you not seen those who were forbidden to hold secret counsels, and afterwards returned to that which they had been forbidden, and conspired together for sin and wrong doing and disobedience to the Messenger (Muhammad SAW). And when they come to you, they greet you with a greeting wherewith Allah greets you not, and say within themselves: "Why should Allah punish us not for what we say?" Hell will be sufficient for them, they will burn therein, and worst indeed is that destination!

Abdullah Yusuf Ali - Translation

Turnest thou not thy sight towards those who were forbidden secret counsels yet revert to that which they were forbidden (to do)? And they hold secret counsels among themselves for iniquity and hostility, and disobedience to the Messenger. And when they come to thee, they salute thee, not as Allah salutes thee, (but in crooked ways): And they say to themselves, "Why does not Allah punish us for our words?" Enough for them is Hell: In it will they burn, and evil is that destination!

Safi-ur-Rahman al-Mubarakpuri

Have you not seen those who were forbidden to hold secret counsels, and afterwards returned to that which they had been forbidden, and conspired together for sin and wrongdoing and disobedience to the Messenger. And when they come to you, they greet you with a greeting wherewith Allah greets you not, and say within themselves: "Why should Allah punish us not for what we say" Hell will be sufficient for them; they will enter therein. And worst indeed is that destination!
