Islam spreads throughout Madinah
:
Islam began among the people of the Aws and the Khazraj in Madinah. Sa'd ibn Mu'adh and Usayd ibn Hudayr became Muslims. They were the leaders of their people, the Banu Abdul-Ashhal of Aws. They were convinced of the truth because of the wisdom and kindness of those who had become Muslims before them, particularly by the excellent presentation of Islam by Mus'ab ibn Umayr. All the people of the Banu Abdul-Ashhal became Muslims, and not a household of the Ansar remained in which some men and women had not accepted the faith.
