(CNN) – The annual Hajj pilgrimage to Mecca is now underway, after beginning on Sunday. The Hajj occurs two months and ten days after Ramadan ends, during the Islamic month of Dhul-Hijjah.
Saudi Arabia estimates that two million people will make the journey this year.
Muslims assemble in Mecca to pray at the Kaaba, Islam’s holiest shrine.
Once there, the faithful perform a series of rituals as an expression of piety and the solidarity of Muslims worldwide.
Every Muslim who is able is expected to try to make the journey at least once in their lives.
