Place of Worship
The Muslim place of worship is called a Mosque or Masjid.
Three of the most holy places of worship for Muslims are the Great Mosque which surrounds the Kaaba in Mecca, the Mosque of the Prophet Muhammad in Medina, and Masjid Al-Aqsa in Jerusalem.
The Kabaa : It was built by Adam and rebuilt by Abraham and his son Ishmael. Wherever Muslims are in the world they face the direction of the Kaaba when they pray. Muslims do not worship the Kaaba, but consider it the House of God and most holy place on earth. During the Hajj and throughout the year, pilgrims circle the Kaaba seven times in a ritual circumambulation.
A Muslim may pray any where in the world whether in a Mosque, a house, an office, or outside. The whole world is a place of worship.
