Surah Al-Kahf, ayah 29

18:29

وَقُلِ ٱلۡحَقُّ مِن رَّبِّكُمۡۖ فَمَن شَآءَ فَلۡيُؤۡمِن وَمَن شَآءَ فَلۡيَكۡفُرۡۚ إِنَّآ أَعۡتَدۡنَا لِلظَّٰلِمِينَ نَارًا أَحَاطَ بِهِمۡ سُرَادِقُهَاۚ وَإِن يَسۡتَغِيثُواْ يُغَاثُواْ بِمَآءٖ كَٱلۡمُهۡلِ يَشۡوِي ٱلۡوُجُوهَۚ بِئۡسَ ٱلشَّرَابُ وَسَآءَتۡ مُرۡتَفَقًا ٢٩

Waqulil-haqqu mir rabbikum faman shā'a falyu'min waman shā'a falyakfur innā a'tadnā liz-zālimīna nāran ahāta bihim surādiquhā wa in yastaghīthū yughāthū bimā'in kal-muhli yashwil-wujūha bi sash-sharābu wasā'at murtafaqā

And say, "The truth is from your Lord, so whoever wills - let him believe; and whoever wills - let him disbelieve." Indeed, We have prepared for the wrongdoers a fire whose walls will surround them. And if they call for relief, they will be relieved with water like murky oil, which scalds [their] faces. Wretched is the drink, and evil is the resting place.
