Allah, may He be exalted, says (interpretation of the meaning) in surah al kahf
Allah, may He be exalted, says (interpretation of the meaning):
“And say: ‘The truth is from your Lord.’ Then whosoever wills, let him believe; and whosoever wills, let him disbelieve. Verily, We have prepared for the Zaalimoon (polytheists and wrongdoers), a Fire whose walls will be surrounding them (disbelievers in the Oneness of Allah). And if they ask for help (relief, water), they will be granted water like boiling oil, that will scald their faces. Terrible is the drink,… and an evil Murtafaq (dwelling, resting place)!
Verily, as for those who believed and did righteous deeds, certainly We shall not make the reward of anyone who does his (righteous) deeds in the most perfect manner to be lost.
These! For them will be ‘Adn (Eden) Paradise (everlasting Gardens); wherein rivers flow underneath them; therein they will be adorned with bracelets of gold, and they will wear green garments of fine and thick silk. They will recline therein on raised thrones. How good is the reward, and what an excellent Murtafaq (dwelling, resting place)!”
