And of them are those who believe in it, and of them (10:40)

Almuntakhab Fi Tafsir Alquran Alkarim

Nonetheless, among them are some who give credence to it and hold it as true and divine, while others do simply refuse to receive it with favour or consenting mind. But Allah, your Creator, knows best those who are characterized with prepensed malice

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

(10:40) Of those some will believe and others will not. Your Lord knows best the mischief-makers. *48

And of them are those who believe in it, and of them meaning

*48). The statement that 'Your Lord knows best the mischief-makers' underscores art important fact about unbelievers. Those unbelievers could certainly silence others into not carrying the discussion any further by openly admitting that they had failed to grasp the teaching of the Qur'an and hence it was not possible for them to sincerely believe in it. God, however, is well aware even of the things that are hidden, even those that are in the deepest recesses of their hearts and minds. He knows how each person has sealed his mind and heart against accepting any truth; how he has sought to immerse himself in heedlessness; how he has managed to suppress his conscience; how he has prevented the testimony of the truth from affecting his heart; how he has destroyed the innate capacity of his mind to accept the truth; how he has heard the call of the truth and has turned a deaf ear to it; and how, despite his ability to understand the Message of God, he has made no effort to do so. Such people cherish their biases and prejudices, their lusts and desires, their worldly advantages and the interests which can be procured only by supporting falsehood, much more than by accepting the truth. Such people can hardly be considered to have innocently succumbed to a 'mistake'. On the contrary, they are rank 'mischief-makers'.
