At-Takwir 81:21

وَالصُّبْحِ إِذَا تَنَفَّسَ

And by the dawn when it breathes

إِنَّهُ لَقَوْلُ رَسُولٍ كَرِيمٍ

[That] indeed, the Qur'an is a word [conveyed by] a noble messenger

ذِي قُوَّةٍ عِندَ ذِي الْعَرْشِ مَكِينٍ

[Who is] possessed of power and with the Owner of the Throne, secure [in position],

وَمَا صَاحِبُكُم بِمَجْنُونٍ

And your companion is not [at all] mad.

وَلَقَدْ رَآهُ بِالْأُفُقِ الْمُبِينِ

And he has already seen Gabriel in the clear horizon.

وَمَا هُوَ عَلَى الْغَيْبِ بِضَنِينٍ

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