Do not say of anything: 'I will do it tomorrow' 23 Except (with the saying), "If Allah will!" And remember your Lord when you forget and say: "It may be that my Lord guides me unto a nearer way of truth than this." 24 And they tarried in their cave three hundred years and added nine. 25 Say: "Allah knows best how long they remained in it, for only He knows all that is hidden in the heavens and the earth. How well He sees; how well He hears! The creatures have no other guardian than Him; He allows none to share His authority." 26 And recite the Book of your Lord which has been divinely revealed to you; there is none who can change His Words; and you will never find a refuge besides 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: '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 will be admitted to the gardens of Eden wherein streams flow. They will rest on soft couches, decked with bracelets of gold and clothed in green silk garments and shining brocade. How blissful is such a reward and resting place! 31
