The Specific words of Allah, the Most Holy, the Most High and the Messenger of Allah that Grant Divine Authority to Everyone of the Imams عليه السلام

3. Al-Husayn ibn Muhammad has narrated from Mu‘alla ibn Muhammad from Ahmad ibn Muhammad from al-Hassan ibn Muhammad al-Hashimi from his father from Ahmad ibn ‘Isa from Abu ‘Abdillah عليه السلام, regarding the words of Allah, the Most Holy, the Most High: “Only God, His Messenger, and the true believers who are steadfast in prayer and pay alms, while they kneel during prayer, are your guardians.” (5:55) It means to have greater priority and authority to deal with your affairs, your souls and your property. Such priority and authority belong to Allah, His Messenger and the believers, Ali and his descendents who are the Imams until the Day of Judgment.
Allah, the Most Holy, the Most High, has then described them saying, “. . the true believers who are steadfast in prayer and pay alms, while they kneel during prayer,. .” Amir al-Mu’minin Ali عليه السلام was praying Zuhr he was in the second Ruku‘ (bowing down). He was wearing a gown that valued a thousand Dinars. The Prophet صلى الله عليه وعلى آله وسلم had made him to wear it. King Najashi had sent it as present to him. A beggar came and said the Islamic greeting words, “Be in peace O Allah’s authority and the authority over the believers who possesses greater priority over them than their own selves. Give some charity to a destitute.“
He threw the gown to the beggar and pointed with his hand to pick up and take it. At such time Allah, the Most Holy, the Most High, sent this verse. He combined His blessings with his belessing in the form of his children. Whoever of his children with whom Imamat found place was due to this blessing was like him (in giving charity). They would give charity while bowed down in Ruku‘ of prayer. The beggar that asked Amir al-Mu’minin Ali عليه السلام for charity was from among the angels. Those who ask the Imams from his children will also be from the angels.”
