Inviting the Kinsfolk to Islam and Declaring 'Ali (a) as the Vicegerent
- O Children of 'Abd al-Muttalib! I do not think anyone from among the Arabs has [ever] brought his people something better than what I have brought for you. I have brought you [the happiness of] this world and the hereafter... I invite you to two words (i.e. phrases), and with these two words you will enter paradise and be saved from hell. These two words are saying that "there is no god but God" (لا اله الا الله), and testifying that I am the prophet of God.
Then he (s) said, "Which one of you will help me in this [mission] and become my vicegerent and deputy?" Everyone was silent. Then 'Ali (a) said, "O Messenger of God, I will!" The Prophet (s) then said, "This is my vicegerent and caliph among you. Listen to what he (a) says and follow his orders." After this speech, some of the Prophet's (s) kinsfolk told Abu Talib [sarcastically], "Obey your child, since he (a) has become superior to you!"
