Nor say of anything, "I shall be sure to do so and so tomorrow"- 23 Except (with the saying), "If Allah will!" And remember your Lord when you forget and say: "It may be that my Lord guides me unto a nearer way of truth than this." 24 And they stayed in their Cave three hundred (solar) years, and add nine (for lunar 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 (and teach) what has been revealed to thee of the Book of thy Lord: none can change His Words, and none wilt thou find as a refuge other than 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," Truth comes from your Lord. Let people have faith or disbelieve as they chose." For the unjust We have prepared a fire which will engulf them with its (flames). Whenever they cry for help they will be answered with water as hot as molted brass which will scald their faces. How terrible is such a drink and such a resting place! 29 As for those who believe and do good works We do not waste the wage of whosoever does good works. 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
