And never say about anything: "I shall certainly do this tomorrow" 23 without [adding,] "if God so wills." And if thou shouldst forget [thyself at the time, and become aware of it later,] call thy Sustainer to mind and say: "I pray that my Sustainer guide me, even closer than this, to a consciousness of what is right!" 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 And recite what has been revealed to you of the Book of your Lord, there is none who can alter His words; and you shall not find any refuge besides 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 Say, "The truth is from your Lord": Let him who will believe, and let him who will, reject (it): for the wrong-doers We have prepared a Fire whose (smoke and flames), like the walls and roof of a tent, will hem them in: if they implore relief they will be granted water like melted brass, that will scald their faces, how dreadful the drink! How uncomfortable a couch to recline on! 29 Surely those who believe, and do deeds of righteousness -- surely We leave not to waste the wage of him who does good works; 30 These! For them will be 'Adn (Eden) Paradise (everlasting Gardens); wherein rivers flow underneath them, therein they will be adorned with bracelets of gold, and they will wear green garments of fine and thick silk. They will recline therein on raised thrones. How good is the reward, and what an excellent Murtafaqa (dwelling, resting place, etc.)! 31
