It is not for mere men to question the pronouncements of the Manifestations of God:
Weigh not the Book of God with such standards and sciences as are current amongst you, for the Book itself is the unerring Balance established amongst men.
Bahá'u'lláh
"Whoso sayeth `why' or `wherefore' hath spoken blasphemy!" Were these people to shake off the slumber of negligence and realize that which their hands have wrought, they would surely perish, and would of their own accord cast themselves into fire--their end and real abode. Have they not heard that which He hath revealed: "He shall not be asked of His doings?" (Qur'an 21:23) In the light of these utterances, how can man be so bold as to question Him, and busy himself with idle sayings?
