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

(1) And whomsoever it is Allah's will to guide, He expandeth his bosom unto the Surrender, and whomsoever it is His Will to send astray, He maketh his bosom close and narrow as if he were engaged in sheer ascent. Thus Allah layeth ignominy upon those who believe not.
