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 proclaim, “The Truth is from your Lord”; so whoever wills may accept faith, and whoever wills may disbelieve – We have indeed prepared for the disbelievers a fire the walls of which will surround them; if they plead for water, their plea will be answered with water like molten metal which shall scald their faces; what an evil drink it is; and what an evil destination is hell! 29 Indeed those who believed and did good deeds – We do not waste the reward of those whose deeds are good. 30 These! for them are Gardens Everlasting whereunder rivers flow; bedecked they shall be therein with bracelets of gold, and wear they shall green robes of satin and brocade, reclining therein on the couches; excellent the reward, and goodly the resting-place! 31
