The Hajj (Pilgrimage to Makkah) is the fifth pillar of Islam.
The rites of pilgrimage are performed today exactly as did by Prophet Abraham (PBUH) and after him by Prophet Muhammad (PBUH). It is mentioned in the Quran “And Hajj to the House (Kaaba) is a duty that mankind owes to God, those who can afford the expenses (for one’s conveyance, provision and residence); and whoever disbelieves then God stands not in need of any of mankind, jinn and all that exists” (Quran 3:97)
Muslims are united in their devotion to Allah. The black man stands next to the white man and they call on Allah with one voice. The king stands beside a peasant and they declare their submission to the will of Allah using the same words.
The running between the hills of Safaa and Marwah, represents the effort Hajar took to find water for the thirsty infant, running between the hills.
That is the first principle of faith: if Allah settled you in a place, He will never let you be lost, however powerless are all causes and means to offer you anything.
Allah, the Exalted mentions in the Quran “Is not He (better than your gods) Who responds to the distressed one, when he calls Him, and Who removes the evil, and makes you inheritors of the earth, generations after generations.” (Quran, 27: 62)
