Shiavault - a Vault of Shia Islamic Books Ammar Ibn Yasir (ra) - A Companion of the Prophet ('s) Chapter 8: Dawn of Islam in Medina Islam had reached Madina before the Holy Prophet's migration to that city, because the leaders of Aws and Khazraj who were the distinguished personalities of these two tribes, and the Yemenite supporters of the Prophet (S) had started propagating Islam on their return to Madina after taking the oath of allegiance to the Prophet (S) at 'Aqaba.
The life of the Prophet (S) in this city was quite different from that in Makkah. In Makkah he lived in the capacity of a missionary and the enmity and obstinacy of Quraysh did not allow that his message should go beyond the stage of an invitation which was confined to promises and threats and giving good tidings and warning about bad consequences.
However, when he arrived in the city of Madina his invitation assumed a different shape, because here he performed the role of a founder and a lawgiver, and had been relieved to some extent of the process of invitation and propagation, He started the process of regulation, construction, administration, and foundation of legislation, The things assumed this shape especially after the Muslims had migrated from Makkah and joined the Prophet (S) in Madina.
Later the persons, who had migrated to Ethiopia, also came over to this city, and now onerous duties and responsibilities regarding establishment devolved upon the Prophet. These people who gathered round the Holy Prophet (S) in this land of peace were recognized to be the nucleus of the new Islamic State and took the central authority in their hands. The houses of the Muslim residents of Madina, who came to be known as Ansar, were filled with the Muhajirs (immigrants).
The kind-hearted Ansar did not grudge the presence of these guests and accorded them a cordial welcome with great enthusiasm. As all these Muhajirs who were continuously pouring into Madina, had not come for a temporary stay but had decided to live in this city permanently.
As they preferred their new homeland to the old one their arrival was a problem which required tackling, The difficulty was to be solved in such a way that the guests should live a free life in this city having due regard for the freedom of the hosts, and that everyone must discharge his own responsibility.
