Prophet Muhammad was the founder of Islam. For the Muslim people Prophet Muhammad was the man who was sent by God to spread Islam on earth. Muhammad was a merchant. See Wikipedia link below. Muhammad was a righteous man, and his prices were that fair, that no further bargaining was required between the seller and the buyer. Remember that bargaining was an essential part of trade in the Muslim world.
Muhammad was born on 570 C.E. and he is the man who united the Arab world. In the period 600-700 C.E. an Islamic Iron Curtain was created, which no longer allowed the infidels i.e. the Christians, to trade through the Silk Roads. From now on the infidels would have to stop at Egypt, and purchase from the Muslim traders the merchandises of East Asia i.e. spices, silk etc. Before Muhammed and Islam the Romans could freely travel through the Silk Roads. After the Islamic Iron Curtain the Indian Ocean became an Islamic Sea.
During the 20th century Gamal Nasser, the Egyptian leader, wanted to unite Egypt, Israel, Lebanon, Syria and the Arabic countries of the Persian Gulf to a single Arabic country, with him as its leader. Muammar Qaddafi of Libya wanted to unite Morocco, Algeria, Tunisia and Libya in a single Arabic country too.
Muhammad used Islam to unite the people of the Arab World. Gamal Nasser and Muammar Qaddafi mainly used Arab nationalism and socialism to unite the Arab World against the “greedy” capitalists/imperialists of the West. It was no longer a battle between Muslims and Christians, between Muslims and infidels, but a battle between Arab socialists against Western capitalists/imperialists.
Erdogan, Turkey’s President, is using today the Islamic socialist model of the Muslim Brotherhood to unite the Muslim World. Erdogan’s path resembles more to the path followed by Prophet Muhammad.
You can call it Islam against the infidels, you can call it socialists against capitalists, but I prefer to call it the war for the Silk Roads.
