Arafah
The Day of Arafah falls on the 9th day of the Islamic month of Dhul Hijjah. It is the day on which Hajj pilgrims stand at Mount Arafah in Mecca, worshiping throughout the day. It is one of three central integrals of the Hajj, the pilgrimage to Mecca required of all Muslims with the ability to do so once in a lifetime. Those who are not on the Hajj pilgrimage are strongly recommended to fast on the Day of Arafah, as the Prophet Muhammad said that doing so forgives sins for two years, one prior and one forthcoming.
