And do not say of anything: Surely I will do it tomorrow, 23 unless (you add) 'if Allah wills' And remember your Lord when you forget and say: 'It may be that my Lord will guide me to something nearer to rectitude than this' 24 And they stayed in the Cave three hundred years and to that they added nine more. 25 Say thou: Allah knoweth best how long they tarried; His alone is the hidden knowledge of the heavens and the earth. How well He seeth and heareth. They have no patron beside Him, nor in His rule He associateth anyone. 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 attached to those who call on their Lord, morning and evening, seeking His pleasure; and do not let your eyes turn away from them, desiring the attraction of worldly life; and do not obey one whose heart We have made heedless of Our remembrance, one who pursues his own whims and becomes dissolute. 28 Say: 'The truth is from your Lord; so let whosoever will believe, and let whosoever will disbelieve.' Surely We have prepared for the evildoers a fire, whose pavilion encompasses them; if they call for succour, they will be succoured with water like molten copper, that shall scald their faces -- how evil a potion, and how evil a 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
