And never say of anything, "Indeed, I will do that tomorrow," 23 but only, 'If God will'; and mention thy Lord, when thou forgettest, and say, 'It may be that my Lord will guide me unto something nearer to rectitude than this.' 24 (It is said) they stayed in the cave three hundred years and nine. 25 Say: 'None but Allah knows how long they stayed. To Him belong the Unseen in the heavens and the earth. How well He sees, and how well He hears! They have no other guardian, other than Him, and He allows no one (to share) His rule' 26 And recite what has been revealed to you of the Book of your Lord, there is none who can alter His words; and you shall not find any refuge besides Him. 27 Be patient with those who worship their Lord in the mornings and evenings to seek His pleasure. Do not overlook them to seek the worldly pleasures. Do not obey those whom We have caused to neglect Us and instead follow their own desires beyond all limits. 28 Say: "The truth is from your Lord: So believe if you like, or do not believe if you will." We have prepared for the sinners a fire which will envelope them in its tent. If they ask for water they will be helped to liquid like molten brass that would scald their mouths. How evil the drink, and evil 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 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
