Islam teaches Muslims to view the Day of Arafah as a day of gratitude, hence the celebration of Eid the day after. It’s also a day of immense forgiveness with opportunity for great reward. Another name for the Day of Arafah is 'Freedom from Fire. ' The meaning of Arafah is “to know.” Though fasting for those not on pilgrimage is desirable, most Muslims fast on this day as it is a day known to discard sins. The day commemorates finality of the religion of Islam, and of Divine revelation. https://nationaltoday.com/
