This narrative from Attar's Mosibat Nameh recounts a drought during the time of Moses. When Moses's own prayers go unanswered, he is told to seek Barkh the Black, a humble and ecstatic lover of God. Barkh's bold, familiar, and seemingly irreverent prayer (shath) immediately brings rain, illustrating the spiritual rank of those whose intimacy (naz) with the Divine transcends formal religious etiquette.
