Sayaqooloona lillahi qul faanna tusharoon (surah Muminun: 89)

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

(23:89) They will surely reply, "This power belongs to Allah." Say, "How then are you so bewitched?" *82

Sa yaqooloona lillaah; qul fa annaa tus haroon

*82) In order to understand the significance of this question, we should know that the art of magic makes a thing appear different from what it really is. Thus the question will mean: "Who has bewitched you that, in spite of knowing and acknowledging all these things, you do not understand the Reality ? Who has bewitched you that even after acknowledging Allah to be the Owner and the AllPowerful Sovereign, you set up other owners and sovereigns along with Him or make them partners with Him and worship them ? Who has deluded you that you should dare to be treacherous and unfaithful to Allah knowing that none can protect you against Him, and forget that you will be called to account for these things?"
In this connection, it should also be noted that this question has a subtle meaning also. The Quraish accused the Holy Prophet of practising magic and sorcery. This question turns the tables on them, as if to say, "O foolish people, the man who presents the Reality appears to you to be a sorcerer, while those leaders who say things against Reality, against common sense and against your own convictions and beliefs, do not appear to you to be sorcerers at all."
