3-99 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Muhammad ibn Yahya al-Attar quoted on the authority of Muhammad ibn Ahmad, on the authority of Al-Hassan ibn Musa al-Khishab, on the authority of Al-Yazid ibn Ishaq She’r, on the authority of Harun ibn Hamzih al-Qanavi that Abdul Ali ibn A’ayn said,

“I asked as-Sadiq (MGB) about the way to disprove one who falsely claims to be a Trustee of the Divine Leader. The Imam (MGB) said, ‘There are three signs which should all exist in anyone who truly claims to be a Trustee of the Divine Leader. He should be the closest to the Divine Leader. He should possess the Prophet’s armaments and he should be so clearly the one declared by the Divine Leader to be his Trustee that when you enter the town and ask the children or the common people about whom the Divine Leader has established as his Trustee, everyone refers to him (MGB).’”
