At-Takwir 81:18

فَلَا أُقْسِمُ بِالْخُنَّسِ

So I swear by the retreating stars -

الْجَوَارِ الْكُنَّسِ

Those that run [their courses] and disappear -

وَاللَّيْلِ إِذَا عَسْعَسَ

And by the night as it closes in

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],

مُّطَاعٍ ثَمَّ أَمِينٍ

Obeyed there [in the heavens] and trustworthy.
