The word(s) "failure" appears 4 time(s) in 4 verse(s) in Quran in Muhammad Pickthal translation.

(1) A similitude of those who disbelieve in their Lord: Their works are as ashes which the wind bloweth hard upon a stormy day. They have no control of aught that they have earned. That is the extreme failure.

(2) And faces humble themselves before the Living, the Eternal. And he who beareth (a burden of) wrongdoing is indeed a failure (on that day).

(3) Nay, but the Hour (of doom) is their appointed tryst, and the Hour will be more wretched and more bitter (than their earthly failure).

(4) And he is indeed a failure who stunteth it.
