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

(1) And of them are those who vex the Prophet and say: He is only a hearer. Say: A hearer of good for you, who believeth in Allah and is true to the believers, and a mercy for such of you as believe. Those who vex the messenger of Allah, for them there is a painful doom.

(2) Lo! Conspiracy is only of the devil, that he may vex those who believe; but he can harm them not at all unless by Allah's leave. In Allah let believers put their trust.
