1537. Ablutions and Movements to Accompany the Recitation of the Long Obligatory Prayer
"Concerning the movements to accompany the recitations of the Long Obligatory Prayer, in response to an enquiry from the National Spiritual Assembly of the Near East, the House of Justice stated in a letter dated September 1, 1975:
'Ablutions are necessary for all three Obligatory Prayers.' 'Reciting the words specified in the medium Obligatory Prayer pertains only to that prayer, i.e., for the short and long Obligatory Prayers it would be sufficient to wash one's hands and face in preparation for each of these two prayers.'
"However, the Universal House of Justice has stated to National Spiritual Assemblies in the West that no issue should be made of this matter at the present time and since it has not been clarified and applied in detail to the western believers, they are under no obligation to go beyond the instructions given by the beloved Guardian in 'Prayers and Meditations' in which ablutions are prescribed only in connection with the medium Obligatory Prayer.
"The instruction to raise one's hands occurs once in the medium Obligatory Prayer and five times in the long Obligatory Prayer. The term used in the original Arabic for the first, second and fourth occasions in the long Prayer is the same as that used in the medium Prayer. Therefore it would be entirely correct for the worshipper, when raising his hands on these occasions during the recitation of the long Obligatory Prayer, to follow the more specific instructions given in English by the Guardian in his translation of the medium one. On the third and fifth occasions the instruction is given in the long Prayer, the words 'in supplication' are omitted. The House of Justice does not wish at this time to give any specific guidance in this connection; it leaves the matter to the discretion of the friends."
