Original title: Sahifih-'i Shattiyyih
Written by Baha'u'llah in the Baghdad period
Book of the Tigris isn't a book but a letter. Its principal subject is Baha'u'llah's analogy between the effect of a new divine revelation and the flooding of the Tigris. Iraq is arid apart from the Mesopotamian river valley, which is given to violent floods. Baha'u'llah discusses how the annual floods are very destructive on the one hand, but irrigate otherwise barren land on the other. New religions also have this tendency to destroy old edifices but to make new spaces green. The letter also contains discussion on miracles and on the first Arabic Hidden Word.

Commentary on a Verse of Rumi was written by Baha'u'llah for the Baha'i courier, Salman, who asked him to interpret a verse from Rumi's Mathnavi: "Because the colorless has fallen captive to color, Moses has gone to war with Moses."
