And never say about anything that, “I will 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 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 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 Recite what is revealed to you in the Book of your Lord. No one can change His Words. You shall find no refuge other than 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 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 We shall not cause their reward to be lost. 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
