And never say of anything, "I shall do such and such thing tomorrow." 23 Except [when adding], "If Allah wills." And remember your Lord when you forget [it] and say, "Perhaps my Lord will guide me to what is nearer than this to right conduct." 24 They remained in the Cave for three hundred years; and others added nine more years. 25 Say: "Allah knows best how long they remained in it, for only He knows all that is hidden in the heavens and the earth. How well He sees; how well He hears! The creatures have no other guardian than Him; He allows none to share His authority." 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 Persevere with those who call on their Lord morning and evening, seeking His magnificence. Do not turn your eyes away from them, seeking the splendours of this world, and do not follow him whose heart We have made oblivious to Our remembrance, who follows his own lust and exceeds the bound. 28 Say, "The truth is from your Lord": Let him who will believe, and let him who will, reject (it): for the wrong-doers We have prepared a Fire whose (smoke and flames), like the walls and roof of a tent, will hem them in: if they implore relief they will be granted water like melted brass, that will scald their faces, how dreadful the drink! How uncomfortable a couch to recline on! 29 But surely We do not let the reward of those who believe and do the right to go waste. 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
