Dervish Piety

The religious history of Islam knows...special cases, in which...quarreling with God is not altogether prohibited, but permitted to a certain degree. It is permitted to the friends of God, who are on especially intimate terms with Him. Their intimacy with God is so well-founded and secure that it cannot be disturbed by occasional audacities, such as reproaches and lovers' disputes, which sometimes occur between lovers but do not disturb their friendly relations. Besides this class of God's friends, there is, however, another category of people who benefit by a special privilege when speaking to God more audaciously than other people. These are the sainted or religious fools, diwanegan, for whom Attar seems to have a peculiar predilection.
