In order that Allah may separate the filthy from the pure, and placing the filthy atop one another, make a heap and throw them into hell; it is they who are the losers.

Have you not seen that Allah slowly transports the clouds, then gathers them together, then heaps them together, so you see the rain coming forth from between them? And from the sky He sends down hail from the mountains of ice, then sends them upon whomever He wills, and averts them from whomever He wills; it is close that the flash of its lightning take away the eyesight.

And were they to see a portion of the sky falling, they will say, “It is a heap of clouds.”
