This concept explores the theme of predestination in Poem 20, Chapter 21 of Attar's Mokhtar Nameh. The poem emphasizes that the span of human life, along with its ultimate end, was decreed in pre-eternity (ازل). It suggests a deterministic worldview where individuals inevitably undergo every 'good and bad' event exactly as it was ordained, highlighting the limits of human knowledge and agency in the face of the divine decree.
