None can change His words. You shall find no refuge besides Him. 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 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 Verily those who believe and work the righteous works - verily We waste not the hire of one who doth well in regard to his work. 30 They shall dwell in the Gardens of Eternity, beneath which streams flow. There they will be adorned with bracelets of gold, will be arrayed in green garments of silk and rich brocade, and will recline on raised couches. How excellent is their reward, and how nice their resting-place!" 31
