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

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 صلى الله عليه وسلم). And when they come to you, they greet you with a greeting wherewith Allâh greets you not, and say within themselves: "Why should Allâh punish us not for what we say?" Hell will be sufficient for them; they will burn therein. And worst indeed is that destination!
