Surah At Takwir Tafseer

And it is not the word of the outcast Shaytan.

meaning, this Qur'an is not the statement of an outcast Shaytan.

This means that he is not able to produce it, nor is it befitting of him to do so. This is as Allah says,

وَمَا تَنَزَّلَتْ بِهِ الشَّيَـطِينُ

وَمَا يَنبَغِى لَهُمْ وَمَا يَسْتَطِيعُونَ

إِنَّهُمْ عَنِ السَّمْعِ لَمَعْزُولُونَ

And it is not the Shayatin who have brought it down. Neither would it suit them nor they can. Verily, they have been removed far from hearing it. (26:210-212)

Then Allah says,

فَأَيْنَ تَذْهَبُونَ
