1 of the 5 basic requirements (arkan or "pillars") of Islam. Its annual observance corresponds to the main holy day id al-adha, itself a commemoration of Abraham's readiness to sacrifice his son on Divine orders. While the hajj could be a religious obligation to be fulfilled a minimum of once within the course of the life of each Muslim, non secular law grants many exclusions on grounds of hardship. The hajj may be a series of extensively detailed rituals. These embody wearing a special garment that symbolizes unity and modesty, collective circumambulations of the Kaaba, and therefore the symbolic stoning of evil.
