The Hajj: In Arabic, the word, Hajj means a resolve of magnificent duty. Hajj also means visit to the revered place, or the pilgrimage to the Ka’bah in the Grand Mosque (Masjid AlHaram or Haram AlSharef), in the City of Makkah (Mecca), in Arabia, which is one of the basic manifestations of the Islamic faith, and a display of unity of the Muslims throughout the world.
The Kabba: (The Sacred House”), is a building located inside the mosque known as Masjid al Haram in Mecca. The mosque was built around the original Kaaba.
The Kaaba is the holiest place in Islam. The qibla, the direction Muslims face during prayer, is the direction from any point to the Kaaba.
