The Ka’bah 

Kabaa (The House of God)
Kaaba is the cubic edifice at the core of the sacred mosque of Masjid al-Haram in Makkah, present day Saudi Arabia. Although it is called the House of God (Bayt Allah) in Islam, it is not to be worshipped in that way because Islam forbids idolatry and polytheism.
The Kaaba in Islam simply indicates the sacred site of meeting for Muslims and plays a role in the sacred ceremonies and rituals of the pilgrimages of Hajj and Umrah. It is also the direction in which Muslims around the world pray five times a day.
In Surah Al-Ma'idah, Allah says about the Ka'bah “Allah has made the Ka’bah, 
the Sacred House, an asylum of security and benefits (e.g. Hajj and Umrah) for mankind.” [5:97]
