The ritual began early this morning and sizeable number of pilgrims, wearing the ihram or two-piece seamless white garment, participated throughout the day.
After the stoning, the pilgrims performed the ritual of animal sacrifice to commemorate Prophet Ibrahim's willingness to sacrifice his only son, Ismail, to God.
