Ammon News - AMMONNEWS - Mohammad Saleh- Millions of pilgrims arrived this week in Mecca for Islam’s annual Hajj (pilgrimage), which officially starts on Sunday.

The pilgrims were heading to Mina, where they will spend their night before heading to the Mount of Arafat in the early hours of Monday.

Many pilgrims began leaving for Mina on Tuesday night after circumambulating the Holy Kaaba, the first house of worship on Earth, built by Adam. Prophet Ibrahim and his son Ismail rebuilt it some 5,000 years ago. Most Hajj rituals are related to Prophet Ibrahim, his wife Hager and his son Prophet Ismail, and thus reflect the unity of humanity.
