Al-Mujadila 58:8 الم تر الى الذين نهوا عن النجوى ثم يعودون لما نهوا عنه ويتناجون بالاثم والعدوان ومعصيت الرسول واذا جاءوك حيوك بما لم يحيك به الله ويقولون في انفسهم لولا يعذبنا الله بما نقول حسبهم جهنم يصلونها فبيس المصير ٨

Did you not see those who were forbidden from holding secret talks; then they do again what they were forbidden to do? They whisper for sinful act and wrongdoing and disobedience of the prophet, and when they come to you, they greet you the way Allah does not greet you, and say to themselves, “Why does Allah not punish us for what we say?” Enough for them is Jahannam (Hell); they will enter it, and it is an evil end.
