Trade expanded, thus creating an important element in the build up of Arab culture. Mecca, due to the presence of the Ka'abah, played a vital role in the formation of a political, cultural, and social order, as well as the creation of a nationalistic sense in the region. Mecca became a cultural, religious and historical capital for Arabs and Moslems, and the first of its kind to be known by Arabs. The Hashemites, or Bani Hashem (sons of Hashem) were able to present themselves as the capable leadership, that has the ability to manage the pilgrimage and other seasons, such as Souk Ukaz - a political, social, economic, and cultural event, resembling present cultural events and international exhibition. Poets, men of letters, laureates, orators lit the darkness of the Arabian desert, with Arabic verse and prose, building through the language a nationalistic sense of unity among travelers to the Arab peninsula. Quraish became elevated with its culture and far sightedness.

Amidst these highly cultural surroundings, the message of Islam emerged. The faithful Arab Hashemite, Mohammad (PBUS), carried the message of tolerance, love, self denial, and the call for grace, and restraint of the detestable. The Prophet began with his own tribe "Warn the closest to you". He led battles, to unite Arabs under the banner of "No God but Allah, the One, with no partner".

Mohammad (PBUS) laid the foundations for a future Islamic society model. Upon succeeding in the Arab peninsula, he carried the banner of Islam internationally. Mu'tah, in the 8th Hijri year, was the first gate he had to go through. Then Yarmouk, in the 13th Hijri, to secure the northern borders. Qadisiyyeh, 15th Hijri, to secure the eastern borders. The State of Islam was thus created, consisting of Bilad al Sham, Arab peninsula, and Iraq. Arabs were united within one structure, with the language and the nationalistic senses bringing them together, based on the righteous Islamic religion. Moslems lived alongside non-Moslems, Ahl al Thima, or whoever wanted to retain their religion.

The Islamic nation was thus created, based on the Quranic verse:

"Mankind! We created You from a single (pair)of a male and a female, and made you into nations and tribes, that ye may know each other (Not that ye may despise each other). Verily the most honoured of you in the sight of God is (he who is) the most righteous of you. And God has full knowledge and is well acquainted (with all things)"
