What is Hajj and Umrah?

Umrah: this is the lesser pilgrimage which is optional and can be performed at any time.
Hajj: The pilgrimage to the holy city of Mecca in Saudi Arabia, which every adult Muslim who is physically and financially able must make at least once in his or her lifetime. About 2,000,000 persons perform the hajj each year, and the rite serves as a unifying force in Islam by bringing followers of diverse backgrounds together in religious celebration. Hakeem’s first pilgrimage was in 1991.
