The second caliph, (581-644), he was father of one of Mohammad’s wife. He built Islamic empire with the help of his generals comprising Syria and all North Africa. Omar, later expelled the Jews and the Christians from the Hijaz (containing the holy cities of Mecca and Medina) in 640, referring to the dhimma of Khaybar he is said to have quoted the Prophet on the right to cancel any pact he wished, and the Prophet’s famous saying: “Two religions shall not remain together in the peninsula of the Arabs”. To this day, the establishment of any other religion in Saudi Arabia is forbidden. From the late eighteenth century through the nineteenth century, expulsion, outbreaks of mob violence, and even massacres became increasingly frequent. Between 1770 and 1786 Jews were expelled from Jedda, most of them fleeing to the Yemen. In 1790 Jews were massacred in Tetuan, in Morocco; in 1828, in Baghdad. In 1834 a cycle of violence and pillage began in Safed. In 1839 a massacre of Jews took place in Meshed in Iran followed by the forced conversion of the survivors, and a massacre of Jews occurred in Barfurush in 1867. In 1840 the Jews of Damascus were subject to the first of a long series of blood libels in many cities. Other outbreaks followed in Morocco, Algeria, Tunisia, Libya and the Arabs countries of the Middle East.
The question to be asked now is “why the expansionism succeeded?” The reason: it has been written in the book of revelation which means this is not just an instinct conducted at the ancient time but rather and a brutal religion existing today.
