And never say thou of a thing: verily I am going to do that on the morrow. 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 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 is revealed to you in the Book of your Lord. No one can change His Words. You shall find no refuge other than Him. 27 Keep yourself attached to those who call on their Lord, morning and evening, seeking His pleasure; and do not let your eyes turn away from them, desiring the attraction of worldly life; and do not obey one whose heart We have made heedless of Our remembrance, one who pursues his own whims and becomes dissolute. 28 Say: 'This is the truth from your Lord. Let whosoever will, believe, and whosoever will, disbelieve it' For the harmdoers, We have prepared a Fire, the pavilion of which encompasses them. When they cry out for relief, they shall be showered with water as hot as molten copper, which will scald their faces; how evil a drink, and how evil a restingplace! 29 Surely (as for) those who believe and do good, We do not waste the reward of him who does a good work. 30 These! for them are Gardens Everlasting whereunder rivers flow; bedecked they shall be therein with bracelets of gold, and wear they shall green robes of satin and brocade, reclining therein on the couches; excellent the reward, and goodly the resting-place! 31
