The supplicatory prayer of Imam al-Husayn (A), the Chief of Martyrs, on the`Arafat Day is one of the famous prayers. Bishr and Bashir, the sons of Ghalib al-Asadi, narrated that they, once, accompanied Imam al-Husayn (A) at the `Arafat Night when he left his tent with submission and reverence. He walked slowly until he, accompanied by a group of his household, sons, and servants, stopped at the left side of Mount `Arafat and turned his face towards the Holy Ka`bah.
