Anyone claiming a Revelation direct from God is a lying imposter.

Whoso layeth claim to a Revelation direct from God ere the expiration of a full thousand years, such a man is assuredly a lying imposter. We pray God that He may graciously assist him to retract and repudiate such a claim. Should he repent, God will, assuredly forgive him. If, however, he persisteth in his error, God will, assuredly, send down one who will deal mercilessly with him. Terrible, indeed, is God in punishing!

- Baha'u'llah (Kitab-i-Aqdas)
