The Hajj pilgrimage commenced on Wednesday, expecting 1.8 million Muslims in Mecca until June 8. Central to the pilgrimage is the Zamzam well, located within the Grand Mosque, which provides water believed to flow for over 4,000 years and is linked to the story of Prophet Abraham and Hagar. During Hajj, pilgrims drink Zamzam water and perform rituals that honor Hagar’s quest for water, reflecting its significance in Islamic tradition and its continuous supply, which is closely monitored to meet the needs of millions of pilgrims.
