"Yathrib" is the old name for Medina (Al-Madinah Al-Monawarah) city in Saudi Arabia, before the migration of Prophet Muhammad. Worth mentioning that it's not preferable to name the city "Yathrib" now. The name itself comes from the family head (Yathrib Ibn Abeel) which was said to be the first family to inhibit this area. They are descendants of Prophet Noah.
Yathrib's residents had asked Muhammad to move to the city in order to bring strong leadership and peace. They sought Muhammad's counsel in brokering a peace between the warring tribed of Aws and Khazraj.
As soon as Muhammad started preaching his message to the pagans, some accepted Islam while others started torturing him and his other followers. It was at that time that the message of Islam spread to the Yathrib. The people of Yathrib very well knew the consequenses of inviting Muhammad and his followers to their city but they decided to go ahead. Thus the credit goes to Muhammad that he successfully convinced the people of Medina to face the danger and help the Muslims. It was nothing but his leadership that his followers agreed to leave their hometown of Mecca Yathrib's residents had asked Muhammad to move to the city in order to bring strong leadership and peace according to NovaNet.
