Do not say of any thing: "I will do it 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 the Cave three hundred years and to that they added nine more. 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 Read whatever is revealed to you from the Book of your Lord. No one can change His words and you can never find any refuge other than Him. 27 Keep yourself content with those who call upon their Lord, morning and evening, seeking His pleasure, and do not let your eyes pass beyond them. Do you seek the pomp and glitter of the world? Do not follow him whose heart We have caused to be heedless of Our remembrance, and who follows his desires, and whose attitude is of excess. 28 And say: "The truth [has now come] from your Sustainer: let, then, him who wills, believe in it, and let him who wills, reject it." Verily, for all who sin against themselves [by rejecting Our truth] We have readied a fire whose billowing folds will encompass them from all sides; and if they beg for water, they will be given water [hot] like molten lead, which will scald their faces: how dreadful a drink, and how evil a place to rest! 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
