quran:21:32 –

And We made the sky a protected ceiling, but they, from its signs, are turning away.  

And We made the heaven a roof, for the earth, ˹functioning˺ like the roof of a house, preserved, from collapsing; and yet of the signs thereof, namely, ˹the signs of this heaven such as˺ the sun, the moon and the stars, they are disregardful, failing to reflect on them and thus realise that the Creator of such ˹things˺ can have no partner.
القرآن:٢١:٣٢ –

وَجَعَلْنَا السَّمَاءَ سَقْفًا مَحْفُوظًا ۖ وَهُمْ عَنْ آيَاتِهَا مُعْرِضُونَ  

{وجلعنا السماء سقفاً} للأرض كالسقف للبيت {محفوظاً} عن الوقوع {وهم عن آياتها} من الشمس والقمر والنجوم {معرضون} لا يتفكرون فيها فيعلمون أن خالقها لا شريك له.
