The word(s) "transgressor" appears 23 time(s) in 23 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) Then We made Our apostles to follow in their footsteps, and We sent Isa son of Marium afterwards, and We gave him the Injeel, and We put in the hearts of those who followed him kindness and mercy; and (as for) monkery, they innovated it-- We did not prescribe it to them-- only to seek Allah's pleasure, but they did not observe it with its due observance; so We gave to those of them who believed their reward, and most of them are transgressors.

(22) Whatever palm-tree you cut down or leave standing upon its roots, It is by Allah's command, and that He may abase the transgressors.

(23) And be not like those who forsook Allah, so He made them forsake their own souls: these it is that are the transgressors.
