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)
