Pilgrims performing Waqoof-e-Arafat (Photos)

A sea of worshippers scaled the rocky hill southeast of the holy city of Mecca for a day of prayers and reflection where Prophet Mohammad (SAWA) delivered his final sermon.

Some of the pilgrims -- men in white seamless garments and women in loose dresses -- pushed elderly relatives in wheelchairs on the second day of the hajj, one of the world’s largest annual gatherings.

A hot wind blew across the hill, also known as Jabal al-Rahma (Mount of Mercy), and the surrounding plain after a downpour late Sunday. Many faithful could be seen sipping from bottles of water.

After sunset, the pilgrims will leave for nearby Muzdalifah where they will gather pebbles to perform the symbolic "stoning of the devil".

The ritual begins in earnest on Tuesday as Muslims observe the first day of Eid al-Azha, or Feast of Sacrifice, which marks the end of the hajj.

Muslims traditionally slaughter sheep for the three-day Eid al-Azha, a tribute to the Prophet Ibraham’s (AS) sacrifice of a lamb after God spared Prophet Ismael (AS), his son.

They will consume some of the meat and give the rest to poor and needy ones.
