Is claiming a false identity and offering unreal services considered a lie, and must one abandon such work in which fraud is suspected?

Lying is informing about something contrary to its reality, knowingly and intentionally. It leads to immorality and then to Hellfire. If it is coupled with deception and trickery, then fraud is combined with lying, which is another sin. It is obligatory to repent to Allah from this disobedience. If the work necessitates lying, deception, mingling with foreign men, or being alone with them, then it is not permissible to remain in it.
