Original title: Suratu'd-Dam
Written by Baha'u'llah in the Edirne period
Surah of Blood is one of the early proclamatory tablets sent by Baha'u'llah from Edirne when he publicly announced His mission. It is addressed to Muhammad "Nabil-i A`zam" Zarandi. In a middle passage (paragraphs 8 to 15), Baha'u'llah identifies Himself with all the past prophets and their sufferings. This passage has a frame story based on the Shi`ite narrative of the martyrdom of Imam Husayn at Karbala. Baha'u'llah depicts himself sprawled out upon the field of battle, mortally wounded (as Imam Husayn was).
