And do not say, regarding anything, 'I am going to do that tomorrow,' 23 without adding, "if God wills." Recall your Lord if you forget to do something. Say, "I hope that my Lord will provide me better guidance." 24 AND [some people assert,] "They remained in their cave three hundred years"; and some have added nine [to that number]. 25 Say: "Allah knows best how long they stayed: with Him is (the knowledge of) the secrets of the heavens and the earth: how clearly He sees, how finely He hears (everything)! They have no protector other than Him; nor does He share His Command with any person whatsoever. 26 And recite the Book of your Lord which has been divinely revealed to you; there is none who can change His Words; and you will never find a refuge besides Him. 27 Restrain thyself along with those who cry unto their Lord at morn and evening, seeking His Countenance; and let not thine eyes overlook them, desiring the pomp of the life of the world; and obey not him whose heart We have made heedless of Our remembrance, who followeth his own lust and whose case hath been abandoned. 28 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 Zalimun (polytheists and wrong-doers, etc.), a Fire whose walls will be surrounding them (disbelievers in the Oneness of Allah). And if they ask for help (relief, water, etc.) they will be granted water like boiling oil, that will scald their faces. Terrible the drink, and an evil Murtafaqa (dwelling, resting place, etc.)! 29 Verily! As for those who believe and do righteous deeds, certainly! We shall not suffer to be lost the reward of anyone who does his (righteous) deeds in the most perfect manner. 30 There will be gardens of Eden for them, with rivers flowing by, where they will be decked in bracelets of gold, with silken robes of green and of brocades to wear, reclining on couches. How excellent the guerdon, and excellent the resting-place! 31
