A holy place of worship
Mecca is a place in Saudi Arabia where many Muslims visit as a holy pilgrimage. It is said that God established this place with Abraham as the Ka'ba (the holy place) and all Muslims face in the direction of Mecca during prayer times.
Mecca and Jerusalem are holy cities for Muslims.
I think it is important for Muslims to have a holy building because then they will have there own place to worship God and to read they're prayers. Even some people stay to listen to speeches from famous Muslims which they sleep in the Mosque for.
Israel; in Hebrew, Eretz Israel.
There is no holy river for Muslims or for Islam religion.
The crusades took place in palestine wich the Muslims, Chrictians, Jews called the holy place.
