In Book 3, Section 28 of the Masnavi, Rumi employs the tale of a cunning Mongol who tricks Egyptians into revealing themselves so he can execute them. This story acts as a direct parallel to Pharaoh's deceptive feast, which was designed to separate the Israelites from their wives to prevent the conception of Moses. On a deeper spiritual level, Rumi uses this anecdote to warn the reader against the allure of Satan's trickery and the desires of the nafs (ego). He emphasizes that yielding to seemingly attractive worldly temptations leads to spiritual ruin, much like the physical demise of the deceived Egyptians, and urges believers to heed the divine call instead.
