The word(s) "layer" appears 3 time(s) in 2 verse(s) in Quran in Muhammad Pickthal translation.

(1) Or as darkness on a vast, abysmal sea. There covereth him a wave, above which is a wave, above which is a cloud. layer upon layer of darkness. When he holdeth out his hand he scarce can see it. And he for whom Allah hath not appointed light, for him there is no light.

(2) Hast thou not seen how Allah wafteth the clouds, then gathereth them, then maketh them layers, and thou seest the rain come forth from between them; He sendeth down from the heaven mountains wherein is hail, and smiteth therewith whom He will, and averteth it from whom He will. The flashing of His lightning all but snatcheth away the sight.
