Al-Kahf 18:29 وقل الحق من ربكم فمن شاء فليومن ومن شاء فليكفر انا اعتدنا للظالمين نارا احاط بهم سرادقها وان يستغيثوا يغاثوا بماء كالمهل يشوي الوجوه بيس الشراب وساءت مرتفقا ٢٩

Say, "The truth is from your Lord": Let him who will believe, and let him who will, reject (it): for the wrong-doers We have prepared a Fire whose (smoke and flames), like the walls and roof of a tent, will hem them in: if they implore relief they will be granted water like melted brass, that will scald their faces, how dreadful the drink! How uncomfortable a couch to recline on!
