The white-robed pilgrims began their ascent at the crack of dawn, covering the Mountain of Mercy at Arafat in an endless sea of white as their chants, "Labbaik Allahumma Labbaik” (O God, here I am answering Your call), reverberated overhead.
The climb at Arafat is one of the cornerstones of the pilgrimage, which is required from every able-bodied Muslim at least once in their life time. It’s the site where Prophet Muhammad (peace be upon him) delivered his farewell sermon and Muslims believe on this day the doors of heavens open to answer prayers and grant forgiveness.
