Am yaqooloona taqawwalahu bal la yu'minoon (surah Tur: 33)

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

(52:33) Do they say: 'He has himself fabricated the Qur'an?' No; the truth is that they are altogether averse to believing. *26

Am yaqooloona taqawwalah; bal laa yu`minoon

*26) In other words, it means this: The Quraish who think that Muhammad (upon whom be peace) himself is the author of the Qur'an know it in their innermost hearts that it cannot be his word, and those others also whose mother tongue is Arabic not only clearly feel that it is far more sublime and superior to human speech but any one of them who knows Muhammad (upon whom be Allah's peace and blessings) personally cannot ever suspect that this is actually his own word and speech. Therefore, the thing plainly is that those who ascribe the authorship of the Qur'an to the Holy Prophet do not, in fact, wish to affirm faith. That is why they are inventing false excuses one of which is this excuse.
