Do not say of anything: '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 (it is said) they tarried in their Cave three hundred years and add nine. 25 Say: "Allah knows best how long they stayed: with Him is (the knowledge of) the secrets of the heavens and the earth: how clearly He sees, how finely He hears (everything)! They have no protector other than Him; nor does He share His Command with any person whatsoever. 26 Recite what has been revealed to thee of the Book of thy Lord; no man can change His words. Apart from Him, thou wilt find no refuge. 27 And restrain yourself along with those who pray to their Lord morning and evening, seeking His pleasure; and may not your sight fall on anything besides them; would you desire the adornment of the life of this world? And do not follow him whose heart We have made neglectful of Our remembrance – the one who has followed his own desires and his matter has crossed the limits. 28 And say thou: the truth is from your Lord; let him therefore who will, believe, and let him who will, disbelieve. Verily We have gotten ready for the wrong-doers a Fire the awnings whereof shall encompass them; and if they cry for relief they shall be relieved with water like the dregs of oil scalding their faces. Ill the drink, and vile 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 Those, they shall live in the Gardens of Eden, underneath which rivers flow. They shall be adorned with bracelets of gold and arrayed in green garments of silk, and brocade, reclining therein on couches; how excellent is their reward and how fine is their resting place! 31
