And say not of anything: Lo! I shall 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 (it is said) they tarried in their Cave three hundred years and add nine. 25 Say, "Allah is most knowing of how long they remained. He has [knowledge of] the unseen [aspects] of the heavens and the earth. How Seeing is He and how Hearing! They have not besides Him any protector, and He shares not His legislation with anyone." 26 Recite what has been revealed to you of the Book of your Lord. There is no one who can change the word of God; and you will not find refuge except in Him. 27 And restrain yourself along with those who pray to their Lord morning and evening, seeking His pleasure; and may not your sight fall on anything besides them; would you desire the adornment of the life of this world? And do not follow him whose heart We have made neglectful of Our remembrance – the one who has followed his own desires and his matter has crossed the limits. 28 Say: "The truth is from your Lord: So believe if you like, or do not believe if you will." We have prepared for the sinners a fire which will envelope them in its tent. If they ask for water they will be helped to liquid like molten brass that would scald their mouths. How evil the drink, and evil the resting-place! 29 Surely (as for) those who believe and do good, We do not waste the reward of him who does a good work. 30 theirs shall be gardens of perpetual bliss - [gardens] through which running waters flow - wherein they will be adorned with bracelets of gold and will wear green garments of silk and brocade, [and] wherein upon couches they will recline:" how excellent a recompense, and how goodly a place to rest! 31
