 2. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Yazid. Sha‘ar from Harun ibn Hamza from ‘Abd al-A‘la who has said that he asked abu ‘Abdallah  the following. “In the case of those who rush to hold control of this matter (leadership) and who claim to be for it, how would one verify their possessing Divine authority?” The Imam  said, “They are asked about the rules of lawful and unlawful matters.” The narrator has said that the Imam  then turned to me and said, “There are three evidence that are not found in one person except the rightful owner of this status. He must be the closest person to the preceding Imam that the Armament must be with him and he would be the appointed executor of the will in a public manner. So much so that if one would come to the town and ask the common people even the children as to who the executor of the will of so and so is? They would say so and so is the executor of the will of so and so.”
