Muhammad b. `Ali narrated to us from Muhammad b. Abi al-Qasim from Muhammad b. `Ali al-Kufi from `Amer b. Kathir al-Sarraj al-Nahdi from Abi al-Jarud from Thabit b. Abi Safiyya from Sayyid al-`Abidin `Ali b. al-Husayn from the Master of Martyrs al-Husayn b. `Ali from the Master of Deputies, the Commander of the Faithful, `Ali b. Abi Talib from the Master of Prophets Muhammad b. `Abdullah, the Seal of Prophets (s). He said:

Surely, Allah has obligated you to obey me, He has prohibited you from disobeying me, and He made it mandatory for you to follow my orders. He has obliged you to obey `Ali after me in the same way that He obliged you to obey me, and He has prohibited you from disobeying him in the same way that He prohibited you from disobeying me. He made him my brother, my vizier, my deputy, and my inheritor. He is from me, and I am from him. Loving him is faith and hating him is disbelief. Loving him is loving me and hating him is hating me. He is the master of anyone that I am a master of, and I am the master of every Muslim man and woman. Him and I are the two fathers of this Nation.
