The word(s) "dark" appears 33 time(s) in 31 verse(s) in Quran in Muhammad Pickthal translation.

(21) 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.

(30) Veiled in darkness,
