In Attar's Elahi Nameh, the tale of Prophet Shuaib illustrates the Sufi ideal of pure devotion and unconditional love for God. Shuaib weeps for ten years until he goes blind, and God repeatedly restores his sight. When God asks Shuaib if his tears are driven by the fear of Hell or the desire for Paradise, Shuaib replies that he weeps solely out of an intense longing for the Divine. This narrative emphasizes a central tenet of Sufism: the highest form of worship is not motivated by the prospect of reward or punishment, but by an all-consuming love and yearning for God Himself.
