And the devils have not brought the revelation down. (26:210)

Almuntakhab Fi Tafsir Alquran Alkarim

And such divine discourse as sacred as the Quran just cannot be the work of evil Spirits nor are they permitted to touch it, not to mention being responsible for bringing it down

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

(26:210) This (lucid Book) has not been brought down by satans, *130

And the devils have not brought the revelation down. meaning

*130) After the positive aspect as stated in vv. 192-193, the negative aspect is being stated that the Qur'an has not been brought down by satans as the enemies of the Truth allege. The unbelieving Quraish in their campaign to spread lies and slander against the Holy Prophet were facing a real difficulty. They did not know how to account for the wonderful discourses which were being presented before the people in the form of the Qur'an and which were moving their hearts deeply. They could not stop the Qur'an from reaching the people. The only thing they could do to counteract its effect and influence was to create doubts and suspicions about it in their minds and hearts. Therefore, in their desperation they charged that Muhammad (Allah's peace be upon him) was a sorcerer, who was being inspired by the satans, and they considered this charge of theirs to be the most effective because it could neither be easily verified nor refuted.
