And never say of anything, "Indeed, I will do that tomorrow," 23 Without adding, "So please Allah!" and call thy Lord to mind when thou forgettest, and say, "I hope that my Lord will guide me ever closer (even) than this to the right road." 24 And they stayed in their Cave three hundred (solar) years, and add nine (for lunar years). 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 (O Prophet), recite to them from the Book of your Lord what has been revealed to you for none may change His words; (and were you to make any change in His words) you will find no refuge from Him. 27 And restrain thyself with those who call upon their Lord at morning and evening, desiring His countenance, and let not thine eyes turn away from them, desiring the adornment of the present life; and obey not him whose heart We have made neglectful of Our remembrance so that he follows his own lust, and his affair has become all excess. 28 And proclaim: "This is the Truth from your Lord. Now let him who will, believe; and let him who will, disbelieve. We have prepared a Fire for the wrong-doers whose billowing folds encompass them. If they ask for water, they will be served with a drink like dregs of oil that will scald their faces. How dreadful a drink, and how evil an abode! 29 The righteously striving believers should know that We do not neglect the reward of those who do good deeds. 30 Those will have gardens of perpetual residence; beneath them rivers will flow. They will be adorned therein with bracelets of gold and will wear green garments of fine silk and brocade, reclining therein on adorned couches. Excellent is the reward, and good is the resting place. 31
