Quran 18:29 Al-Kahf, ayah 29 of 110

وَقُلِ ٱلْحَقُّ مِن رَّبِّكُمْ ۖ فَمَن شَآءَ فَلْيُؤْمِن وَمَن شَآءَ فَلْيَكْفُرْ ۚ إِنَّآ أَعْتَدْنَا لِلظَّـٰلِمِينَ نَارًا أَحَاطَ بِهِمْ سُرَادِقُهَا ۚ وَإِن يَسْتَغِيثُوا۟ يُغَاثُوا۟ بِمَآءٍ كَٱلْمُهْلِ يَشْوِى ٱلْوُجُوهَ ۚ بِئْسَ ٱلشَّرَابُ وَسَآءَتْ مُرْتَفَقًا ۝٢٩

18:29 Say: (It is) the truth from the Lord of you (all). Then whosoever will, let him believe, and whosoever will, let him disbelieve. Lo! We have prepared for disbelievers Fire. Its tent encloseth them. If they ask for showers, they will be showered with water like to molten lead which burneth the faces. Calamitous the drink and ill the resting-place!
