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

(1) Yet ye it is who slay each other and drive out a party of your people from their homes, supporting one another against them by sin and transgression? - and if they came to you as captives ye would ransom them, whereas their expulsion was itself unlawful for you - Believe ye in part of the Scripture and disbelieve ye in part thereof? And what is the reward of those who do so save ignominy in the life of the world, and on the Day of Resurrection they will be consigned to the most grievous doom. For Allah is not unaware of what ye do.

(2) O ye who believe! Fulfil your indentures. The beast of cattle is made lawful unto you (for food) except that which is announced unto you (herein), game being unlawful when ye are on the pilgrimage. Lo! Allah ordaineth that which pleaseth Him.

(3) Say: Have ye considered what provision Allah hath sent down for you, how ye have made of it lawful and unlawful? Hath Allah permitted you, or do ye invent a lie concerning Allah?
