Shiavault - a Vault of Shia Islamic Books A Probe into the History of Ashura' Chapter 44: Tribes of Aws and Khazraj After the destruction of the Ma'arib dam of Yemen a large part of the lands of Yemen became uncultivable. The opening of the sea route of the Red Sea and the deterioration of the economic importance of Yemen was the pretext for their migration, and it is possible that each of these two things had an effect on the scattering of the Qahtani tribes of Yemen.
In any case on whatever pretext it might have been, the Almighty Allah brought these two tribes of Yemen to Yathrib and made them settle there, and eventually when it became intolerable for the Holy Prophet to continue to live in Makkah amongst his relations, these two tribes received him and his immigrant companions, gave them place in their houses and preferred them even to themselves.
From the day these two tribes called Aws and Khazraj came to Yathrib and settled there, they were continuously fighting with each other till they were fed up with this state of affairs and realized that if they continued to fight they would be annihilated and the Jews of Yathrib belonging to the tribes of Bani Nazir etc. would prevail over them. Some of them were, therefore, obliged to go to Makkah to seek assistance from Quraysh so that they might become exalted and powerful.
However, Quraysh put forward certain conditions which were not acceptable to them. Then they went to Taif and sought the assistance of the tribe of Thaqif. However, they also dilly- dallied and the persons from Yathrib returned home without achieving any result. In the meantime the Holy Prophet had made his call public in the 4th year of his mission.
For ten years continuously he contacted the people in the bazaars of Arabia like ukkaz and Zul Hijaz and the pilgrims during Haj season at Mina, Makkah etc. and invited them to Islam. He asked them to assist him and support his Divine mission so that they might be rewarded with Paradise. He approached various tribes one after the other and said to them: "O people!
Say that there is no deity but Allah so that you may be delivered, rule over the Arabs and non-Arabs and become the chiefs in Paradise as a result of your faith. None of the Arab tribes except Aws and Khazraj of Yathrib agreed to receive the afflicted homeless Muslims. It was only this sacred city which could embrace the Holy Prophet of Allah forever.
