`Ali b. Ahmad b. `Abdullah b. Ahmad b. Abi `Abdillah al-Barqi narrated to us from his father from his grandfather Ahmad b. Abi `Abdillah from his father Muhammad b. Khalid from Ghiyath b. Ibrahim from Thabit b. Dinar from Sa`d b. Turayf from Sa`id b. Jubayr from Ibn `Abbas. He said:

The Messenger of Allah (s) said to `Ali b. Abi Talib : O `Ali! I am the City of Wisdom and you are its Gate. None can enter the City except through its Gate. One who alleges that he loves me while hating you has lied, for you are from me and I am from you. Your flesh is from my flesh, your blood is from my blood, and your spirit is from my spirit. Your secret is my secret, and your public is my public. You are the Imam of my Nation and my vicegerent (khalifati) over it after me. One who obeys you is happy, and one who disobeys you is wretched. One who aligns with you has triumphed, and one who opposes you has lost. One who sticks to you has won, and one who abandons you is destroyed. Your example and the example of the Imams from your descendants is like that of the Ark of Nuh: whoever boards it is saved, and whoever abandons it drowns. Your example is like that of the stars: whenever one star disappears, another star rises, until the Day of Resurrection.
