"Surely the first House of worship established for mankind was that at Makkah--a blessed site and a guidance for all creation.

In it are clear signs and the Station of Abraham. Whoever enters it shall be safe. And performance of pilgrimage to this House is a duty to God for all who can afford the journey to it; and whoever disbelieves, then God is free from need of any of His creation."

Al-Qur'an (3: 96-97)
