The requirements for obligatory prayer called for in the Bábí
and Islamic Dispensations were more demanding than those
for the performance of the Obligatory Prayer consisting of
nine rak’áhs that was prescribed in the Kitáb-i-Aqdas (see
note 4).
In the Bayán, the Báb prescribed an Obligatory Prayer
consisting of nineteen rak’áhs which was to be performed
once in a twenty-four-hour period—from noon of one day to
noon of the next.
The Muslim prayer is recited five times a day, namely,
in the early morning, at midday, in the afternoon and
evening, and at night. While the number of rak’áhs varies
according to the time of recitation, a total of seventeen
rak’áhs are offered in the course of a day.
