The Bab refers to this incident in the " Dala'il-i-Sab'ih" in the following terms: "Recall the first days of the Manifestation, how many people died of cholera! That was one of the wonders of the Manifestation yet no one understood it. During four years the scourge raged among the Muhammadan Shiites without anyone grasping its true significance." ("Le Livre des Sept Preuves," translated by A. L. M. Nicolas, pp. 61-62.)
