"The daily obligatory prayers are three in number. The shortest one
consists of a single verse which has to be recited once in every
twenty-four hours and at midday. The medium (prayer) which begins with the
words: 'The Lord is witness that there is none other God but He,' has to
be recited three times a day, in the morning, at noon and in the evening.
The long prayer which is the most elaborate of the three has to be recited
once in every twenty-four hours, and at any time one feels inclined to do
so.
"The believer is entirely free to choose any one of those three prayers
but is under the obligation of reciting one of them, and in accordance
with any specific directions with which they may be accompanied.
"These daily obligatory prayers, together with a few other specific ones,
such as the Healing Prayer, the Tablet of Ahmad, have been invested by
Baha'u'llah with a special potency and significance, and should therefore
be accepted as such and be recited by the believers with unquestioned
faith and confidence, that through them they may enter into a much closer
communion with God, and identify themselves more fully with His Laws and
precepts."
