Do not say of any thing: "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 remained in their cave three hundred years and (some) add (another) nine. 25 Say: "God knows best how long they remained [there]. His [alone] is the knowledge of the hidden reality of the heavens and the earth: how well does He see and hear! No guardian have they apart from Him, since He allots to no one a share in His rule!" 26 Proclaim what has been revealed to you from your Lord's Book. None can change His words. You shall find no refuge besides Him. 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: 'This is the truth from your Lord. Let whosoever will, believe, and whosoever will, disbelieve it' For the harmdoers, We have prepared a Fire, the pavilion of which encompasses them. When they cry out for relief, they shall be showered with water as hot as molten copper, which will scald their faces; how evil a drink, and how evil a restingplace! 29 As for those who believe and do good We shall not cause their reward to be lost. 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
