Granted is your prayer (Qur'an 20:36)." According to this text, ‘Ali is the Prophet's vicegerent among his people, his vizier among his kin, his partner in his undertaking - not in Prophethood - his successor, the best among his people, and the most worthy of their leadership alive or dead. They owed him obedience during the Prophet's lifetime as the Prophet's vizier, just as Aaron's people had to obey Aaron during the lifetime of Moses.
Whoever becomes familiar with the status hadith will immediately consider its deep implications without casting any doubt at the gist of its context. The Messenger of Allah (pbuh) has made this very clear when he said: "It is not proper for me to leave this place before assigning you as my vicegerent." It is a clear text regarding his succession; nay, it even suggests that had the Prophet (pbuh) left without doing so, he would have done something he was not supposed to have done.

Anyone who examines the phrase "then you have not conveyed His Message at all," then examines the Prophet's statement: "It is not proper for me to leave this place before assigning you as my vicegerent," will find them both aiming at the same conclusion, as is quite obvious.
We should also not forget the Prophet's hadith saying: "You are the wali of every believer after me." It is a clear reference to the fact that he is the Prophet's wali and the one who takes his place, as al-Kumait, may Allah have mercy on his soul, has implied when he said: "A great Vicegerent, a fountain-head of piety, an educator!" And peace be with you. Sincerley, Sh Previous…
