9. We have set forth the details of obligatory prayer in another Tablet. [#8]
The original Obligatory Prayer had "for reasons of wisdom" been revealed by Bahá’u’lláh in a separate Tablet (Q and A 63). It was not released to the believers in His lifetime, having been superseded by the three Obligatory Prayers now in use.
Shortly after the Ascension of Bahá’u’lláh, the text of this prayer, along with a number of other Tablets, was stolen by Muḥammad-‘Alí, the Arch-breaker of His Covenant.
10. the Prayer for the Dead [#8]
The Prayer for the Dead (see Some Texts Supplementary to the Kitáb-i-Aqdas) is the only Bahá’í obligatory prayer which is to be recited in congregation; it is to be recited by one believer while all present stand in silence (see note 19). Bahá’u’lláh has clarified that the Prayer for the Dead is required only when the deceased is an adult (Q and A 70), that the recital should precede the interment of the deceased, and that there is no requirement to face the Qiblih when saying this prayer (Q and A 85).
Further details concerning the Prayer for the Dead are summarized in the Synopsis and Codification, section IV.A. 13.-14.
11. six specific passages have been sent down by God, the Revealer of Verses [#8]
The passages that form part of the Prayer for the Dead comprise the repetition of the greeting "Alláh-u-Abhá" (God is the All-Glorious) six times, each followed by nineteen repetitions of one of six specifically revealed verses. These verses are identical with those in the Prayer for the Dead revealed by the Báb in the Bayán. Bahá’u’lláh added a supplication to precede these passages.
