And say not of anything: Lo! I shall do that tomorrow, 23 but only, 'If God will'; and mention thy Lord, when thou forgettest, and say, 'It may be that my Lord will guide me unto something nearer to rectitude than this.' 24 And they remained in their cave three hundred years and (some) add (another) nine. 25 Say: "Allah knows best how long they stayed: with Him is (the knowledge of) the secrets of the heavens and the earth: how clearly He sees, how finely He hears (everything)! They have no protector other than Him; nor does He share His Command with any person whatsoever. 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 And contain thyself in patience by the side of all who at morn and at evening invoke their Sustainer, seeking His countenance, and let not thine eyes pass beyond them in quest of the beauties of this world's life; and pay no heed to any whose heart We have rendered heedless of all remembrance of Us because he had always followed [only] his own desires, abandoning all that is good and true. 28 And say: The truth is from your Lord, so let him who please believe, and let him who please disbelieve; surely We have prepared for the iniquitous a fire, the curtains of which shall encompass them about; and if they cry for water, they shall be given water like molten brass which will scald their faces; evil the drink and ill the 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
