Duaa Arafah is one of the most valuable, important and highly significant supplications which we recite only once in a year (on the Day of Arafah i.e 9th Dhu’l-Hijjah). This supplication which is present in Mafateeh al-Jinaan is from the Master of Martyrs, Imam Hussain (as). This is such a precious gem that there are no words available to express its greatness.
