Hajj is the annual Islamic pilgrimage to the holy city of Makka, a fundamental pillar of Islam and one of the Five Pillars. It is obligatory for all financially and physically capable Muslims to undertake the journey at least once in their lifetime. Hajj occurs during the Islamic month of Dhu al-Hijjah and involves a series of rituals, including circumambulating the Kaaba, standing on the plain of Arafat, symbolic stoning of the devil, and sacrificing an animal. The pilgrimage fosters a sense of unity, equality, and spiritual purification among Muslims, emphasizing their submission to God and solidarity with the global Muslim community.
