Al-Mujadilah - 58:8

أَلَمْ تَرَ إِلَى الَّذِينَ نُهُوا عَنِ النَّجْوَى ثُمَّ يَعُودُونَ لِمَا نُهُوا عَنْهُ وَيَتَنَاجَوْنَ بِالْإِثْمِ وَالْعُدْوَانِ وَمَعْصِيَتِ الرَّسُولِ وَإِذَا جَاؤُوكَ حَيَّوْكَ بِمَا لَمْ يُحَيِّكَ بِهِ اللَّهُ وَيَقُولُونَ فِي أَنفُسِهِمْ لَوْلَا يُعَذِّبُنَا اللَّهُ بِمَا نَقُولُ حَسْبُهُمْ جَهَنَّمُ يَصْلَوْنَهَا فَبِئْسَ الْمَصِيرُ
[58:8]
Have you not seen those who are forbidden secret counsels, then they return to what they are forbidden, and they hold secret counsels for sin and revolt and disobedience to the Messenger, and when they come to you they greet you with a greeting with which Allah does not greet you, and they say in themselves: Why does not Allah punish us for what we say? Hell is enough for them; they shall enter it, and evil is the resort.
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!
Hast thou not observed those who were forbidden conspiracy and afterward returned to that which they had been forbidden, and (now) conspire together for crime and wrongdoing and disobedience toward the messenger? And when they come unto thee they greet thee with a greeting wherewith Allah greeteth thee not, and say within themselves: Why should Allah punish us for what we say? Hell will suffice them; they will feel the heat thereof - a hapless journey's end!
