‘Kaaba’ is a small marble building built in the large mosque of Mecca. This building was constructed by Abraham for Allah’s worship. This building has a sacred ‘Black stone’. It is believed that this stone was thrown on the earth from Jannat (heaven) with Adam at the time of Kaba’s creation and Gabriel gave it to Abraham. Every person who journeys from Mecca to Medina pays ‘Ziyarat’ (Prayers) here. There is also a rule in Islam that every Muslim wherever he is, should always keep his face towards to Kaaba and pay Namaz.
