On the day of Arafat, [The day preceding the festival] the Báb, seeking the quiet seclusion of His cell, devoted His whole time to meditation and worship. On the following day, the day of Nahr, after He had offered the feast-day prayer, He proceeded to Muná, where, according to ancient custom, He purchased nineteen lambs of the choicest breed, of which He sacrificed nine in His own name, seven in the name of Quddús, and three in the name of His Ethiopian servant. He refused to partake of the meat of this consecrated sacrifice, preferring instead to distribute it freely among the poor and needy of that neighbourhood.
