Do not say of any thing: "I will do it tomorrow," 23 Without (adding), "if God may please;" and think of your Lord in ease you forget, and say: "Perhaps my Lord will show me a nearer way to rectitude." 24 And they stayed in their Cave for three hundred years* and nine more*. (* 300 according to the Solar calendar and 309 according to the Lunar calendar.) 25 Say: Allah knows best how long they remained; to Him are (known) the unseen things of the heavens and the earth; how clear His sight and how clear His hearing! There is none to be a guardian for them besides Him, and He does not make any one His associate in His Judgment. 26 Proclaim what has been revealed to you from your Lord's Book. None can change His words. You shall find no refuge besides Him. 27 And keep thy soul content with those who call on their Lord morning and evening, seeking His Face; and let not thine eyes pass beyond them, seeking the pomp and glitter of this Life; nor obey any whose heart We have permitted to neglect the remembrance of Us, one who follows his own desires, whose case has gone beyond all bounds. 28 And proclaim, “The Truth is from your Lord”; so whoever wills may accept faith, and whoever wills may disbelieve – We have indeed prepared for the disbelievers a fire the walls of which will surround them; if they plead for water, their plea will be answered with water like molten metal which shall scald their faces; what an evil drink it is; and what an evil destination is hell! 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 For them are everlasting Gardens of Eden, beneath which rivers flow – in it they will be given bracelets of gold to adorn, and shall wear green clothes made of fine silk and gold embroidery, reclining upon thrones in it; what an excellent reward; and what an excellent abode is Paradise! 31
