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

(1) And because of their breaking their covenant, We have cursed them and made hard their hearts. They change words from their context and forget a part of that whereof they were admonished. Thou wilt not cease to discover treachery from all save a few of them. But bear with them and pardon them. Lo! Allah loveth the kindly.

(2) And if thou fearest treachery from any folk, then throw back to them (their treaty) fairly. Lo! Allah loveth not the treacherous.

(3) If the enemy had entered from all sides and they had been exhorted to treachery, they would have committed it, and would have hesitated thereupon but little.
