وَإِن يَرَوۡاْ كِسۡفًا مِّنَ ٱلسَّمَآءِ سَاقِطًا يَقُولُواْ سَحَابٌ مَّرۡكُومٌ
Were they to see a piece of the sky falling (on them), they would (only) say: "Clouds gathered in heaps!"<br/>
And if they were to see a fragment, a portion, of the sky falling, on them - as they say, Then make fragments of the sky 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.
