In the Hadiqat al-Haqiqah, Sana'i recounts a story where the Caliph Umar ibn al-Khattab tests a group of people who claim to be unified brothers. Umar asserts that true brotherhood and sincere love are not merely verbal claims, but must be proven by a complete lack of possessiveness over worldly wealth. He states that only when companions can freely access and spend from each other's purses without reservation or grief are they truly brothers in spirit. This story serves as an allegory illustrating that hypocrisy in love or friendship is exposed by one's reluctance to share material possessions.
