The Messenger of Allah (s) said: O `Ali! You are my brother, and I am your brother. O `Ali! You are from me, and I am from you. O `Ali! You are my deputy, my vicegerent (khalifa), and the Proof of Allah over my Nation after me. Whoever aligns with you will be made happy, and whoever opposes you will be made wretched.
