if a king violates to the extent of one atom he shall be cut off immediately.

The confirmation of the Kingdom of Abhá' shall descend uninterruptedly upon those souls who are firm in the Covenant. Thou hast well observed that every firm one is assisted and aided and every violator is degraded, humiliated and lost... This Covenant is the Covenant of His Holiness Baha'u'llah. Now its importance is not known befittingly, but in the future it shall attain to such a degree of importance that if a king violates to the extent of one atom he shall be cut off immediately.

(‘Abdu’l-Bahá, Tablet, Star of West, Vol. IV, p. 240)
