Explanation:

The Medina Charter was drawn up by the Islamic prophet Muhammad. It was made up of a formal agreement between Muhammad and all the important tribes and families of Iatrebe (later known as Medina), including Muslims, Jews and pagans. The document was drawn up with the explicit concern of ending the cruel struggle between the tribes of Aus and Khazraj in the interior of Medina. To this end, it instituted a series of rights and responsibilities for the Muslim, Jewish and pagan communities of Medina bringing them into a single community - Ummah.
