The Holy City of MakkahThe Holy City of Makkah, which lies inland 73 kilometers east of Jiddah, is the place where the Prophet Muhammad, peace be upon him, was born - the place where God's message was first revealed to him and the city to which he returned after the migration to Madinah in 622 AD.
Makkah is the holiest city on earth to Muslims. Five times each day, the world's one billion Muslims, wherever they may be, turn to the Holy City of Makkah to pray. And at least once in their lives, all Muslims who are not prevented by personal circumstance perform the Hajj, the pilgrimage to Makkah. Thus each year the Holy City of Makkah is host to some two million hajjis (pilgrims) from all over the world.
The Holy City of MadinahMadinah, which lies 447 kilometers north of the Holy City of Makkah, is the second holiest city in Islam. It was to Madinah that the Prophet Muhammad, peace be upon him, and his followers, faced by the hostility and persecution of the Makkhan merchants, departed in 622 AD - and, when the citizens of Madinah asked the Prophet to live amongst them and to arbitrate in their affairs (an invitation taken to mean their rejection of polytheism and submission to the will of the one God, Allah), it was in Madinah that the Islamic era began.
Madinah is then the city of the Prophet. As the place in which the Holy Qur'an was compiled and from which the Prophet's companions administered the affairs of the Muslim community, it was the seat of the first Islamic state. From Madinah, armies, spreading the word of the Prophet, were dispatched to Egypt, Persia and Syria.
Madinah is also the place in which the Prophet, peace be upon him, was buried.
