The Prophet's mission began in Mecca.
The Prophet's mission began in Mecca. There is nothing in the pre- hijra program of the Prophet that looks similar to a political movement. It was primarily and fundamentally a religious movement. Only after the hijra, when the majority of the people of Medina accepted Islam, the opportunity for implementation of Islamic social order arose and so (s.a.w.) also assumed the position of the political leader of the society.
He signed agreements with other tribes, sent ambassadors to kings and emperors, organized armies and led Muslim forces, sat in judgement, appointed governors, deputees, commanders, and judges, and he also collected and distributed taxes. Nonetheless, Islam was first a religious movement that later on encompassed political aspects of society. So to say that "Islam as a religious phenomenon was subsequent to Islam as a political reality" is historically an incorrect statement.
The Origin of Shí'ism The origin of Shí'ism is not separate from the origin of Islam since the Prophet himself sowed its seed by proclaiming the wisaya (successorship) and khilafat (caliphate) of 'Ali bin Abí Talib in the first open call to Islam that he made in Mecca. Islam began when the (peace be upon him and his progeny) became forty years old. Initially, the mission was kept a secret.
Then three years after the advent of Islam, the Prophet was ordered to commence the open declaration of his message. This was the occasion when Almighty Allah revealed the verse **"** And warn thy nearest relations." (The Qur'an 26:214) When this verse was revealed, the Prophet organized a feast that is known in history as "Summoning the Family - Da'wat dhu 'l-'Ashira ". The Prophet invited about forty men from the Banu Hashim and asked 'Ali bin Abi Talib to make arrangements for the dinner.
After having served his guests with food and drinks, but the Prophet wanted to speak to them about Islam, Abu Lahab forestalled him and said, "Your host has long since bewitched you." All the guests dispersed before the Prophet could present his message to them. The Prophet then invited them the next day. After the feast, he spoke to them, saying: O Sons of 'Abdu 'l-Muttalib!
By Allah, I do not know of any person among the Arabs who has come to his people with better than what I have brought to you. I have brought to you the good of this world and the next, and I have been commanded by the Lord to call you unto Him.
