He [Baha’u’llah] was put in chains and thrown into a subterranean dungeon. His extensive hereditary possessions were entirely plundered, He was four times exiled from land to land, and in the end He came to abide in the Most Great Prison
Notwithstanding all this, the call of God was ceaselessly raised and the fame of His Cause was noised abroad. Such were the knowledge, learning, and perfections He evinced that everyone in Persia was astonished. All the learned people—friend and foe alike—who attained His presence in Tihrán, Baghdád, Constantinople, Adrianople, and ‘Akká received a complete and convincing answer to their every question. All readily acknowledged that in every perfection He was peerless and unique throughout the world.
