Fasting during the first ten days of Dhul-Hijjah, including the Day of Eid (Eid al-Adha), is considered highly recommended and virtuous in Islam. These ten days are considered among the most sacred and blessed days of the Islamic calendar. Fasting during this time is a way to earn rewards and seek forgiveness. The Day of Arafah, which falls on the 9th day of Dhul-Hijjah, is particularly significant. Fasting on this day is highly encouraged, and it is said to expiate the sins of the previous year and the year to come. It’s worth noting that for those who are performing Hajj, fasting on the Day of Arafah is not recommended as it is not part of the rituals of Hajj. Fasting on the Day of Eid (10th Dhul-Hijjah) is discouraged because it is a day of celebration and thanksgiving. Muslims typically break their fast on this day and offer special prayers. Keep in mind that while fasting during these days is recommended, it is not obligatory, and individuals may choose to fast or not based on their circumstances and ability.
