5. at noon and in the morning and the evening [#6]
Regarding the definition of the words "morning", "noon" and "evening", at which times the currently binding medium Obligatory Prayer is to be recited, Bahá’u’lláh has stated that these coincide with "sunrise, noon and sunset" (Q and A 83). He specifies that the "allowable times for Obligatory Prayers are from morning till noon, from noon till sunset, and from sunset till two hours thereafter". Further, ‘Abdu’l-Bahá has stated that the morning Obligatory Prayer may be said as early as dawn.
The definition of "noon" as the period "from noon till sunset" applies to the recitation of the short Obligatory Prayer as well as the medium one.

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.
