n19.
Save in the Prayer for the Dead, the practice of congregational prayer hath been annulled.
Congregational prayer, in the sense of formal obligatory prayer which is to be recited in accordance with a prescribed ritual as, for example, is the custom in Islám where Friday prayer in the mosque is led by an imám, has been annulled in the Bahá'í Dispensation. The Prayer for the Dead (see note 10) is the only congregational prayer prescribed by Bahá'í law. It is to be recited by one of those present while the remainder of the party stands in silence; the reader has no special status. The congregation is not required to face the Qiblih (Q&A 85).
The three daily Obligatory Prayers are to be recited individually, not in congregation.
There is no prescribed way for the recital of the many other Bahá'í prayers, and all are free to use such non-obligatory prayers in gatherings or individually as they please. In this regard, Shoghi Effendi states that

. . . although the friends are thus left to follow their own inclination, . . . they should take the utmost care that any manner they practise should not acquire too rigid a character, and thus develop into an institution. This is a point which the friends should always bear in mind, lest they deviate from the clear path indicated in the Teachings.

Say: God hath made My hidden love the key to the Treasure
There is a well-known Islamic tradition concerning God and His creation:

I was a Hidden Treasure. I wished to be made known, and thus I called creation into being in order that I might be known.

References and allusions to this tradition are found throughout the Bahá'í Writings. For example, in one of His prayers, Bahá'u'lláh reveals:

Lauded be Thy name, O Lord my God! I testify that Thou wast a hidden Treasure wrapped within Thine immemorial Being and an impenetrable Mystery enshrined in Thine own Essence. Wishing to reveal Thyself, Thou didst call into being the Greater and the Lesser Worlds, and didst choose Man above all Thy creatures, and didst make Him a sign of both of these worlds, O Thou Who art our Lord, the Most Compassionate!
Thou didst raise Him up to occupy Thy throne before all the people of Thy creation. Thou didst enable Him to unravel Thy mysteries, and to shine with the lights of Thine inspiration and Thy Revelation, and to manifest Thy names and Thine attributes. Through Him Thou didst adorn the preamble of the book of Thy creation, O Thou Who art the Ruler of the universe Thou hast fashioned! (Prayers and Meditations by Bahá'u'lláh, XXXVIII)


Likewise, in the Hidden Words, He states:

O Son of Man! I loved thy creation, hence I created thee. Wherefore, do thou love Me, that I may name thy name and fill thy soul with the spirit of life.

'Abdu'l-Bahá, in His commentary on the above-cited tradition, wrote:

O wayfarer in the path of the Beloved! Know thou that the main purpose of this holy tradition is to make mention of the stages of God's concealment and manifestation within the Embodiments of Truth, They who are the Dawning-places of His All-Glorious Being. For example, before the flame of the undying Fire is lit and manifest, it existeth by itself within itself in the hidden identity of the universal Manifestations, and this is the stage of the "Hidden Treasure". And when the blessed Tree is kindled by itself within itself, and that Divine Fire burneth by its essence within its essence, this is the stage of "I wished to be made known". And when it shineth forth from the Horizon of the universe with infinite Divine Names and Attributes upon the contingent and placeless worlds, this constituteth the emergence of a new and wondrous creation which correspondeth to the stage of "Thus I called creation into being". And when the sanctified souls rend asunder the veils of all earthly attachments and worldly conditions, and hasten to the stage of gazing on the beauty of the Divine Presence and are honoured by recognizing the Manifestation and are able to witness the splendour of God's Most Great Sign in their hearts, then will the purpose of creation, which is the knowledge of Him Who is the Eternal Truth, become manifest.
n33.
It hath been ordained that every believer in God . . . shall, each day . . . repeat
"Alláh-u-Abhá" is an Arabic phrase meaning "God the All-Glorious". It is a form of the Greatest Name of God (see note 137). In Islám there is a tradition that among the many names of God, one was the greatest; however, the identity of this Greatest Name was hidden. Bahá'u'lláh has confirmed that the Greatest Name is "Bahá".
The various derivatives of the word "Bahá" are also regarded as the Greatest Name. Shoghi Effendi's secretary writing on his behalf explains that

The Greatest Name is the Name of Bahá'u'lláh. "Yá Bahá'u'l-Abhá" is an invocation meaning: "O Thou Glory of Glories!". "Alláh-u-Abhá" is a greeting which means: "God the All-Glorious". Both refer to Bahá'u'lláh. By Greatest Name is meant that Bahá'u'lláh has appeared in God's Greatest Name, in other words, that He is the supreme Manifestation of God.

The greeting "Alláh-u-Abhá" was adopted during the period of Bahá'u'lláh's exile in Adrianople.
The repetition of "Alláh-u-Abhá" ninety-five times is to be preceded by the performance of ablutions (see note 34).
n65.
Nimrod
The Nimrod referred to in this verse is, in both Jewish and Islamic traditions, a King who persecuted Abraham and whose name became symbolic of great pride.
n72.
Whoso wisheth to make use of vessels of silver and gold is at liberty to do so.
In the Bayán the Báb allowed the use of gold and silver utensils, thus abrogating the Islamic condemnation of their use which stems not from an explicit injunction of the Qur'án but from Muslim traditions. Bahá'u'lláh here confirms the Báb's ruling.
n79.
We have made it lawful for you to listen to music and singing.
'Abdu'l-Bahá has written that "Among certain nations of the East, music was considered reprehensible". Though the Qur'án contains no specific guidance on the subject, some Muslims consider listening to music as unlawful, while others tolerate music within certain bounds and subject to particular conditions.
There are a number of passages in the Bahá'í Writings in praise of music. 'Abdu'l-Bahá, for example, asserts that "music, sung or played, is spiritual food for soul and heart".
n85.
He hath granted them no right to the property of others.
The injunction to show kindness to Bahá'u'lláh's kindred does not give them a share in the property of others. This is in contrast to Shí'ih Muslim practice, in which lineal descendants of Muhammad are entitled to receive a share of a certain tax.
n90.
he who would take into his service a maid may do so with propriety
Bahá'u'lláh states that a man may employ a maiden for domestic service. This was not permissible under Shí'ih Muslim practice unless the employer entered into a marriage contract with her. Bahá'u'lláh emphasizes that the "service" referred to in this verse is solely "such as is performed by any other class of servants, be they young or old, in exchange for wages" (Q&A 30). An employer has no sexual rights over his maid. She is "free to choose a husband at whatever time she pleaseth", for the purchase of women is forbidden (Q&A 30).
n103.
semen is not unclean
In a number of religious traditions and in Shí'ih Muslim practice semen has been declared ritually unclean. Bahá'u'lláh has here dispelled this concept. See also note 106 below.
n111.
He Who held converse with God
This is a traditional Jewish and Islamic title of Moses. Bahá'u'lláh states that with the coming of His Revelation "human ears have been privileged to hear what He Who conversed with God heard upon Sinai".
n174.
and permitted you to attire yourselves in silk
According to Islamic practice, the wearing of silk by men was generally forbidden, except in times of holy war. This prohibition, which was not based on the verses of the Qur'án, was abrogated by the Báb.
n175.
The Lord hath relieved you . . . of the restrictions that formerly applied to clothing and to the trim of the beard.
Many rules about dress had their origins in the laws and traditional practices of the world's religions. For example, the Shí'ih clergy adopted for themselves a distinctive headdress and robes and, at one time, forbade the people to adopt European attire. Muslim practice, in its desire to emulate the custom of the Prophet, also introduced a number of restrictions with regard to the trim of the moustache and the length of the beard.
Bahá'u'lláh removed such limitations on one's apparel and beard. He leaves such matters to the "discretion" of the individual, and at the same time calls upon the believers not to transgress the bounds of propriety and to exercise moderation in all that pertains to dress.
