Muhammad b. `Ali narrated to us from his uncle Muhammad b. Abi al-Qasim from Muhammad b. `Ali al-Kufi from Muhammad b. Sinan from Ziyad b. al-Mundhir from Sa`id b. Jubayr from Ibn `Abbas. He said:

The Messenger of Allah (s) said: Whoever opposes `Ali b. Abi Talib after me is a disbeliever, and whoever associates partners with him is a polytheist. Whoever loves him is a believer, and whoever hates him is a hypocrite. Whoever pursues what he leaves behind is in pursuit [of Paradise], whoever is at war with him is a traitor, and whoever turns away from him is in falsehood. `Ali is the light of Allah in His cities, and His Proof over the worshipers. `Ali is the Sword of Allah upon His enemies, and the inheritor of the knowledge of His prophets. `Ali is the exalted word of Allah, and the words of his enemies are lowly. `Ali is the Master of the Deputies, and the Deputy of the Master of Prophets. `Ali is the Commander of the Faithful, the Leader of the shining believers, and the Imam of the Muslims. Allah does not accept faith except in his wilaya and his obedience.
