Al-Anbiya' - 21:32

وَجَعَلْنَا السَّمَاء سَقْفًا مَّحْفُوظًا وَهُمْ عَنْ آيَاتِهَا مُعْرِضُونَ
[21:32]
And We have made the heaven a guarded canopy and (yet) they turn aside from its signs.
And We have made the heavens as a canopy well guarded: yet do they turn away from the Signs which these things (point to)!
And we have made the sky a roof withheld (from them). Yet they turn away from its portents.
