At-Takwir 81:27

وَمَا هُوَ عَلَى الْغَيْبِ بِضَنِينٍ

And Muhammad is not a withholder of [knowledge of] the unseen.

وَمَا هُوَ بِقَوْلِ شَيْطَانٍ رَّجِيمٍ

And the Qur'an is not the word of a devil, expelled [from the heavens].

فَأَيْنَ تَذْهَبُونَ

So where are you going?

لِمَن شَاءَ مِنكُمْ أَن يَسْتَقِيمَ

For whoever wills among you to take a right course.

وَمَا تَشَاءُونَ إِلَّا أَن يَشَاءَ اللَّهُ رَبُّ الْعَالَمِينَ

And you do not will except that Allah wills - Lord of the worlds.
