And do not say, regarding anything, 'I am going to do that 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 (it is said) they tarried in their Cave three hundred years and add nine. 25 Say: Allah is Best Aware how long they tarried. His is the Invisible of the heavens and the earth. How clear of sight is He and keen of hearing! They have no protecting friend beside Him, and He maketh none to share in His government. 26 And recite, [O Muhammad], what has been revealed to you of the Book of your Lord. There is no changer of His words, and never will you find in other than Him a refuge. 27 And restrain yourself along with those who pray to their Lord morning and evening, seeking His pleasure; and may not your sight fall on anything besides them; would you desire the adornment of the life of this world? And do not follow him whose heart We have made neglectful of Our remembrance – the one who has followed his own desires and his matter has crossed the limits. 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 for those who believe and do good works We do not waste the wage of whosoever does good works. 30 For them will be Gardens of Eternity; beneath them rivers will flow; they will be adorned therein with bracelets of gold, and they will wear green garments of fine silk and heavy brocade: They will recline therein on raised thrones. How good the recompense! How beautiful a couch to recline on! 31
