In Attar's 'Mosibat Nameh', the encounter between Alexander the Great and the Faghfur (Emperor) of China serves as an allegory for the true nature of sustenance and the futility of worldly wealth. When the Emperor serves Alexander a bowl of precious jewels instead of food, Alexander protests that he cannot eat them. The Emperor uses this to question Alexander's insatiable drive for conquest and hoarding of treasure, pointing out that basic sustenance (a simple loaf of bread) is all a human truly needs. This teaches learners the Sufi perspective on the uselessness of amassing worldly riches, contrasting material greed with genuine human necessity.
