And never say thou of a thing: verily I am going to do that on the morrow. 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 remained in their cave three hundred years and (some) add (another) nine. 25 Say, “Allah well knows how long they stayed; for Him only are the hidden of the heavens and the earth; how well He sees and hears! They do not have any supporter besides Him; and He does not associate anyone in His command.” 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 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: (It is) the truth from the Lord of you (all). Then whosoever will, let him believe, and whosoever will, let him disbelieve. Lo! We have prepared for disbelievers Fire. Its tent encloseth them. If they ask for showers, they will be showered with water like to molten lead which burneth the faces. Calamitous the drink and ill the resting-place! 29 Lo! as for those who believe and do good works - Lo! We suffer not the reward of one whose work is goodly to be lost. 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
