The Bahá’í House of Worship is dedicated to the praise of God. The House of Worship forms the central edifice of the Mas̱ẖriqu’l-Aḏẖkár (the Dawning-place of the Praise of God), a complex which, as it unfolds in the future, will comprise in addition to the House of Worship a number of dependencies dedicated to social, humanitarian, educational, and scientific pursuits. ‘Abdu’l-Bahá describes the Mas̱ẖriqu’l-Aḏẖkár as "one of the most vital institutions in the world", and Shoghi Effendi indicates that it exemplifies in tangible form the integration of "Bahá’í worship and service". Anticipating the future development of this institution, Shoghi Effendi envisages that the House of Worship and its dependencies "shall afford relief to the suffering, sustenance to the poor, shelter to the wayfarer, solace to the bereaved, and education to the ignorant". In the future, Bahá’í Houses of Worship will be constructed in every town and village. 54. The Lord hath ordained that those of you who are able shall make pilgrimage to the sacred House #32 Two sacred Houses are covered by this ordinance, the House of the Báb in S̱ẖíráz and the House of Bahá’u’lláh in Bag̱ẖdád. Bahá’u’lláh has specified that pilgrimage to either of these two Houses fulfils the requirement of this passage (Q and A 25, 29). In two separate Tablets, known as Súriy-i-Hájj (Q and A 10), Bahá’u’lláh has prescribed specific rites for each of these pilgrimages. In this sense, the performance of a pilgrimage is more than simply visiting these two Houses. After the passing of Bahá’u’lláh, ‘Abdu’l-Bahá designated the Shrine of Bahá’u’lláh at Bahjí as a place of pilgrimage. In a Tablet, He indicates that the "Most Holy Shrine, the Blessed House in Bag̱ẖdád and the venerated House of the Báb in S̱ẖíráz" are "consecrated to pilgrimage", and that it is "obligatory" to visit these places "if one can afford it and is able to do so, and if no obstacle stands in one’s way". No rites have been prescribed for pilgrimage to the Most Holy Shrine. 55. and from this He hath exempted women as a mercy on His part #32 In the Bayán, the Báb enjoined the ordinance of pilgrimage once in a lifetime upon those of His followers who were financially able to undertake the journey. He stated that the obligation was not binding on women in order to spare them the rigours of travel. Bahá’u’lláh likewise exempts women from His pilgrimage requirements. The Universal House of Justice has clarified that this exemption is not a prohibition, and that women are free to perform the pilgrimage. 56. to engage in some occupation #33 It is obligatory for men and women to engage in a trade or profession. Bahá’u’lláh exalts "engagement in such work" to the "rank of worship" of God. The spiritual and practical significance of this law, and the mutual responsibility of the individual and society for its implementation are explained in a letter written on behalf of Shoghi Effendi:
