Waqf al Arafa – Hajj Day (Islam)
Waqf al Arafa is the Islamic observance day during Hajj in which pilgrims pray for forgiveness and mercy. Pilgrims stay awake at night to pray on the hill of Arafat, the site where Muhammad traditionally delivered his last sermon.

October 26-29

Eid-Ul-Adha (Islam)
Concluding the Hajj, Eid-Ul-Adha is the Festival of Sacrifice held the day after the visit to Arafat, in which pilgrims move to Mina. Those who can afford to do so sacrifice their best domestic animals, such as sheep or cows. This practice recalls Abraham’s willingness to sacrifice his son, in obedience to God, and commemorates God’s forgiveness.
