The word(s) "treacherous" appears 4 time(s) in 4 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Surely We have revealed the Book to you with the truth that you may judge between people by means of that which Allah has taught you; and be not an advocate on behalf of the treacherous.

(2) And do not plead on behalf of those who act unfaithfully to their souls; surely Allah does not love him who is treacherous, sinful;

(3) And if you fear treachery on the part of a people, then throw back to them on terms of equality; surely Allah does not love the treacherous.

(4) Allah sets forth an example to those who disbelieve the wife of Nuh and the wife of Lut: they were both under two of Our righteous servants, but they acted treacherously towards them so they availed them naught against Allah, and it was said: Enter both the fire with those who enter.
