Did you know that the very first law that Baha’u’llah revealed in the Kitab-i-Aqdas is the obligatory prayer?

We have enjoined obligatory prayer upon you, with nine rak'ahs, to be offered at noon and in the morning and the evening unto God, the Revealer of Verses. We have relieved you of a greater number, as a command in the Book of God. He, verily, is the Ordainer, the Omnipotent, the Unrestrained. (Baha'u'llah, The Kitab-i-Aqdas, p. 20)
