Do not turn your eyes away from them, seeking the splendours of this world, and do not follow him whose heart We have made oblivious to Our remembrance, who follows his own lust and exceeds the bound. 28 Say: 'The truth is from your Lord; so let whosoever will believe, and let whosoever will disbelieve.'

How excellent the guerdon, and excellent the resting-place! 31
