In this allegory from Farid al-Din Attar's Mosibat Nameh, a dying madman (divaneh)—depicted as a destitute yet profound lover of the Divine—instructs a witness to use his only shirt as a shroud and to write his final testimony on it using the blood from his own heart. The madman's message declares that he has finally returned his earthly form ('dust and water') to God, leaving the world to the Divine since he and God could not both coexist within it. This story illustrates the Sufi theme of fana (annihilation of the self), where the lover's final act of devotion is the complete surrender of his existence, with the heart's blood serving as the ultimate proof of his spiritual sincerity.
