Never say of something, "I shall do it tomorrow," 23 unless (you add) 'if Allah wills' And remember your Lord when you forget and say: 'It may be that my Lord will guide me to something nearer to rectitude than this' 24 And they remained in their cave three hundred years and (some) add (another) nine. 25 (Muhammad), say, "God knows best how long they stayed there; to Him belongs the unseen of both the heavens and the earth. How clear is His sight and how keen His hearing! No one other than Him is their guardian and no one shares His Judgment. 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 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 As to those who believe and work righteousness, verily We shall not suffer to perish the reward of any who do a (single) righteous deed. 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
