In Section 25 of Farid al-Din Attar's Mosibat Nameh, a parable is told of a prince who orders a slave to purchase greens with merely half a grain of gold. The king sharply rebukes him, stating that such pettiness befits a greengrocer, not a king. This allegory emphasizes that true nobility and spiritual kingship require magnanimity and a complete detachment from trivial material wealth. For the Sufi wayfarer, a soul aspiring to spiritual royalty must transcend base attachments and mundane transactions.
