How did medina welcome the prophet?

This question can be read two ways:

If the question is asking, "When Mohammed was in Mecca, what was the way in which he received the message, i.e. God's message?", the answer is: While in a cave in Mecca the angel Gabriel told Muhammad that he was to recite to Word of God, or Allah.

If the question is asking, "When Mohammed preached his message to the People of Mecca, how did they receive him, i.e. how did they respond to the message?", the answer is: Mohammed did manage to convert a few people closely related to him, but his attacks on idolatry were not well received, especially by the tribe of Qoreish. This tribe subsequently ordered his death, resulting in him having to flee to Yethrib. It is only after this flight from Mecca that the Umma, or Muslim community, develops.
