Do not say of any thing: "I will do it tomorrow," 23 Unless Allah pleases; and remember your Lord when you forget and say: Maybe my Lord will guide me to a nearer course to the right than this. 24 [Some say], "They stayed in their cave three hundred years," and to that some have added another nine years. 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 Recite what has been revealed to you of the Book of your Lord. There is no one who can change the word of God; and you will not find refuge except in Him. 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 thou: the truth is from your Lord; let him therefore who will, believe, and let him who will, disbelieve. Verily We have gotten ready for the wrong-doers a Fire the awnings whereof shall encompass them; and if they cry for relief they shall be relieved with water like the dregs of oil scalding their faces. Ill the drink, and vile the resting-place! 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 They shall dwell in the Gardens of Eternity, beneath which streams flow. There they will be adorned with bracelets of gold, will be arrayed in green garments of silk and rich brocade, and will recline on raised couches. How excellent is their reward, and how nice their resting-place!" 31
