Never say of something, "I shall do it tomorrow," 23 without [adding], "if God so wills." Remember your Lord whenever you might forget and say, "I trust my Lord will guide me to that which is even nearer to the right path than this." 24 And they remained in their cave three hundred years and (some) add (another) nine. 25 Say: 'God knows very well how long they tarried. To Him belongs the Unseen in the heavens and in the earth. How well He sees! How well He hears! They have no protector, apart from Him, and He associates in His government no one.' 26 And recite that which hath been revealed unto thee of the Scripture of thy Lord. There is none who can change His words, and thou wilt find no refuge beside Him. 27 And keep yourself patient [by being] with those who call upon their Lord in the morning and the evening, seeking His countenance. And let not your eyes pass beyond them, desiring adornments of the worldly life, and do not obey one whose heart We have made heedless of Our remembrance and who follows his desire and whose affair is ever [in] neglect. 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 Surely those who believe, and do deeds of righteousness -- surely We leave not to waste the wage of him who does good works; 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
