And do not say of anything: Surely I will 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 [some people assert,] "They remained in their cave three hundred years"; and some have added nine [to that number]. 25 Say: 'None but Allah knows how long they stayed. To Him belong the Unseen in the heavens and the earth. How well He sees, and how well He hears! They have no other guardian, other than Him, and He allows no one (to share) His rule' 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 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 Say, "This is the truth from your Lord. Let him who will, believe in it, and him who will, deny it." For the wrongdoers We have prepared a Fire which will cover them like a canopy, and if they beg for water, they will be given water as hot as molten lead, which will scald their faces: how dreadful a drink, and how evil a resting place! 29 As for those who believe and do good deeds, We do not let the reward of anyone who does a good deed go to waste, 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
