June 10

On the eve of Our departure from ‘Iráq, We have warned the faithful to anticipate the appearance of the Birds of Darkness. There can be no doubt whatever that the croaking of the Raven shall be raised in certain lands, as it hath been heard in recent years. Whatever may betide, seek refuge in the one true God, that He may shield you from the wiles of the impostor. 

Baha’u’llah  (‘Gleanings from the Writings of Baha’u’llah’)
