Quran 18:29

وَقُلِ ٱلۡحَقُّ مِن رَبِّكُمۡ‌ۖ فَمَن شَآءَ فَلۡيُؤۡمِن وَمَن شَآءَ فَلۡيَكۡفُرۡ‌ۚ إِنَّآ أَعۡتَدۡنَا لِلظَّـٰلِمِينَ نَارًا أَحَاطَ بِہِمۡ سُرَادِقُهَا‌ۚ وَإِن يَسۡتَغِيثُواْ يُغَاثُواْ بِمَآءٍ۬ كَٱلۡمُهۡلِ يَشۡوِى ٱلۡوُجُوهَ‌ۚ بِئۡسَ ٱلشَّرَابُ وَسَآءَتۡ مُرۡتَفَقًا ٢٩

Proclaim: "This is the truth from your Lord," then whoever wills let him believe, and whoever wills let him disbelieve. We have prepared for the transgressors a fire that will completely surround them. When they scream for help, they will be given a liquid like concentrated acid that scalds the faces. What a miserable drink! What a miserable destiny!
