And do not say, regarding anything, 'I am going to do that 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 for three hundred years and exceeded by nine. 25 Say: "Allah knows best how long they stayed. With Him is (the knowledge of) the unseen of the heavens and the earth. How clearly He sees, and hears (everything)! They have no Wali (Helper, Disposer of affairs, Protector, etc.) other than Him, and He makes none to share in His Decision and His Rule." 26 And rehearse thou that which hath been revealed unto thee of the Book of thy Lord; and none may alter His Words, and never wilt thou find beside Him a covert. 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 whosoever will, believe, and whosoever will, disbelieve it' For the harmdoers, We have prepared a Fire, the pavilion of which encompasses them. When they cry out for relief, they shall be showered with water as hot as molten copper, which will scald their faces; how evil a drink, and how evil a restingplace! 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 Those, they shall live in the Gardens of Eden, underneath which rivers flow. They shall be adorned with bracelets of gold and arrayed in green garments of silk, and brocade, reclining therein on couches; how excellent is their reward and how fine is their resting place! 31
