In Attar's Mosibat Nameh, the story of the retrieval of Moses' coffin from the water by Pharaoh's handmaidens serves as an allegory for divine grace and spiritual intercession. Although only one handmaiden retrieves the coffin, Pharaoh frees all four hundred of them because they all participated in the search. This illustrates how the spiritual success or righteousness of a single individual can lead to the liberation and salvation of an entire group associated with them.
