The Prophet of Islam, Muhammad –peace be upon him- was born in Arabia and he made Arabs a community of outstanding excellence both in manners and humanity. 
Wherever they- the holy companions of Prophet Muhammad (s)- went, the thought and life were revolutionized and this is the reason why Islam was spread around the world very rapidly after Prophet Muhammad’s (s) birth.
Prophet Muhammad (s) was very handsome and powerful, and his childhood gave indication of the sublime and dynamic personality that was going to emerge. As and when he grew up, the nobility of his behavior and personality showed greater impacts on anyone who behold him. With God’s will, he presented perfect personality being tolerant, magnanimous and extremely truthful that gave him a noble name ‘Al-Ameen’.
The Arabia, before the advent of Prophet Muhammad (s) was calamitous. Arabs were religiously ignorant and morally worsened. They were divided themselves in to clans and clans in to families and each family had its own idols in their domain. The Idolatry had gained such extreme hold in the Arabia and it was greater challenge on Prophet Muhammad (s). As we see from the very natural and religious perspectives of Islam, the fundamental tenet of Islam is “zero tolerance approach” to idolatry. Islam suggests worshiping a single God and Him alone, not being represented through idols. Women, War and Wine were the three ‘W’s of the time that the Arabs were mad about. A man could have as many wives as he wished and any number of mistresses. Prostitution was quite rife among them and they made money from ‘prostitution’ too. As for education, it was fully unknown to them. This is a small overview picture of the Arabia before Prophet Muhammad’s (s) mission.
Prophet Muhammad (s) had to put such hard efforts to put forth the ideologies of Islam and Moral life. It is Allah’s grace that when ignorance and moral darkness became rampant and the people were led by cruelty and oppression, they should be brought back to the right path. It was Prophet Muhammad (s) who brought significant ‘change’ in the history like rain after intense heat or light of day after night’s darkness. The Holy Prophet of Islam converted Arabs from being divided people and they became a united nation. The uncivilized people of the Arabs underwent a ‘transformation’ that made them most civilized people. His mission of religious renaissance in the Arabia of 23 years had become an illuminating example of revolution unparalleled in the known history that made him the ‘greatest man’ and ‘exemplary conduct’ forever.
I thought it is worth to quote Edward Gibbon’s comment on the unique personality of Prophet Muhammad (s).
“Muhammad was distinguished by the beauty of his person,
An outward gift which is seldom despised, except by those to
Whom it has been refused… His memory was capacious and retentive,
His wit easy and social, his imagination sublime, his judgment clear,
rapid and decisive. He possessed the courage both of thought and action…
bears the stamp of an original and superior genius.” (Edward Gibbon and J. B. Bury, 2004, The Decline and Fall of the Roman Empire, p. 357, published by Wildside Press LLC)
