Concerning the Healing Prayer, the Guardian wishes me to inform you that there is no special ruling for its recital. The believer is free to recite it as many times and in the way he wishes. There are also no obligatory prayers for the Fast. But there are some specific ones revealed by Bahá’u’lláh for that purpose.
