The date of the Manifestation is fixed by the following passage in the Persian Bayan [ Vahid 2, Bab 7): "The beginning thereof was when two hours and eleven minutes [had passed] from the evening preceding the fifth of Jamadiyu'l-Ula, 1260 [A.H.], which is the year 1270 of the mission [of Muhammad]." (From manuscript copy of Bayan written by the hand of Siyyid Husayn, amanuensis and companion of the Bab.)
