quran:52:44 –

And if they were to see a fragment from the sky falling, they would say, "˹It is merely˺ clouds heaped up."  

And if they were to see a fragment, a portion, of the heaven falling, on them — as they say, Then make fragments of the heaven fall upon us ˹Q. 26:187˺, as a chastisement for them — they would say, this is: ‘A heap of clouds!’, piled on top of one another, that will bring us water; and so they do not believe.
القرآن:٥٢:٤٤ –

وَإِنْ يَرَوْا كِسْفًا مِنَ السَّمَاءِ سَاقِطًا يَقُولُوا سَحَابٌ مَرْكُومٌ  

(وإن يروا كسفا) بعضا (من السماء ساقطا) عليهم كما قالوا: "" فأسقط علينا كسفا من السماء "" أي تعذيبا لهم (يقولوا) هذا (سحاب مركوم) متراكب نروى به ولا يؤمنون.
