Ya ayyuha annasu inna waAAda Allahi haqqun fala taghurrannakumu alhayatu addunya wala (surah Fatir: 5)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(35:5) O people, assuredly Allah's promise is true. *10 So let the life of the world not delude you, *11 and let not the Deluder delude you concerning Allah. *12

Yaaa ayyuhan naasu inna wa`dal laahi haqqun falaa taghurrannakumul hayaatud dunyaa; wa laa yaghurran nakum billaahil gharoor

*10) "The promise" implies the promise of the Hereafter to which allusion was made in the preceding sentence, saying: 'All affairs shall ultimately be presented before Allah.
*11) "Let not...deceive you": "Deceive you that the world is an end in itself: that there is no Hereafter when one will have to render an account of one's deeds: or that even if there is the Hereafter, the one who is enjoying life here will enjoy life there, too."
*12) "Great deceiver": Satan, as is evident from the next sentence. And "deceive you concerning Allah" means: ( Il That he should stake some people believe that Allah does not exist at All; (2) involve others in the misunderstanding that Allah after having once created the world, has retired and has now practically nothing to do with the universe any more; (3) delude others into believing that Allah no doubt is running the universe, but He has taken no responsibility of providing guidance to man: therefore, Revelation and Prophethood are a mere deception; and 14) give still others the false hope that since Allah is All-Forgiving and All-Merciful. He will forgive one whatever sins one might have committed, and that He has some beloved ones too: if one remains attached to them, success and salvation are assured.
