And never say of anything, "I shall do such and such thing 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 [Some say], "They stayed in their cave three hundred years," and to that some have added another nine years. 25 You say: "God only knows how long they stayed. He alone knows the secrets of the heavens and the earth. How distinctly He sees and hears! They have no other guardian but Him, and He does not share His authority with any one." 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 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: (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 But surely We do not let the reward of those who believe and do the right to go waste. 30 There will be gardens of Eden for them, with rivers flowing by, where they will be decked in bracelets of gold, with silken robes of green and of brocades to wear, reclining on couches. How excellent the guerdon, and excellent the resting-place! 31
