Sura al-Ṭūr 52:9

يَوْمَ تَمُورُ ٱلسَّمَآءُ مَوْرًا

yawma tamūru l-samāʾu mawran

On the Day when the firmament will be in dreadful commotion.

Sura al-Ṭūr 52:36

أَمْ خَلَقُوا۟ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ بَل لَّا يُوقِنُونَ

am khalaqū l-samāwāti wa-l-arḍa bal lā yūqinūna

Or did they create the heavens and the earth? Nay, they have no firm belief.

Sura al-Ṭūr 52:44

وَإِن يَرَوْا۟ كِسْفًا مِّنَ ٱلسَّمَآءِ سَاقِطًا يَقُولُوا۟ سَحَابٌ مَّرْكُومٌ

wa-in yaraw kisfan mina l-samāʾi sāqiṭan yaqūlū saḥābun markūmun

Were they to see a piece of the sky falling (on them), they would (only) say: "Clouds gathered in heaps!"
