Yaqout al Hamawi in his gazetteer 'Mu'jam al Buldan', and Al Tabari in his "History" say that Qusai was the first in his tribe Quraish to hold a throne, after Ismail's sons, during the era of Al Munther bin Al Numan, King of Heerah. Qusai divided Mecca into four quarters, where he built Dar al Nadwah. This marked the emergence of a special system for the Arab society, in the period between 482-418 AD, or before the birth of Prophet Mohammad (PBUS), in the year 570 AD. The Hashemites created a new pact from different Arab tribes, led by Bani Abd Manaf, aiming to provide security and stability to the pilgrims traveling to Mecca before Islam. The pact also undertook to protect people, and apply justice. It's strength was derived from that of the Hashemite Qurashians and their abilities to forge a Meccan society before Islam.

The Hashemites exercised and invested their authority in the building of an Arab society in the Arab Peninsula. They demonstrated a distinguished ability to communicate with Arab tribes, who visited Mecca for trade and pilgrimage. They reached out to the South - Aseer and Yemen, to the borders of Bilad al Sham - in the north.

Arabs spoke of the Hashemites as a household of generosity, merit, and leadership. A further dimension of this reputation was carried to further lands away, with the summer and winter trade journeys called ‘Eilaf', the summer trade journey went to Bilad Al Sham, and the winter journey to Yemen and Egypt. Thus the Hashemite fame reached all Arab lands, and were recognized for amiable well natured conduct.

Hashem, the Prophet's grandfather, was one of Eilaf leaders. He died in Gaza, Palestine, while on one of an Eilaf journey. His grave in Gaza testifies to this, and the fact that Gaza is called 'Gazat Hashem', or Gaza that belongs to Hashem, votes for the high regard and leadership people of these lands held for him.

Furthermore, the Hashemite Quraish Al Fadoul pact was the first of its kind, established to promote social work, and became a nucleus and example for organization and union structure. Prophet Mohammad (PBUS) witnessed the Fadoul pact when he was twenty years old. Some say he was twenty five years. He attended meetings between different Arab tribes, such as Bani Asad, and Abdul Mutaleb.
