Pilgrimage
The stay at Muzdalifah is preceded by a day at Mount Arafat, consisting of glorifying God, repeating the duʿāʾ (Supplication), repentance to God, and asking him for forgiveness. At Arafat, Ẓuhr and ʿAṣrprayers are performed in a combined and abbreviated form during the time of Zuhr. After sunset on the ninth day of the Islamic month of Dhūl-Ḥijjah, Muslim pilgrims travel to Muzdalifah, sometimes arriving at night because of over-crowding. After arriving at Muzdalifah, pilgrims pray the Maghrib and ʿIshāʾ prayers jointly, whereas the Isha prayer is shortened to 2 rakats. At Muzdalifah, pilgrims collect pebbles for the Stoning of the Devil (Arabic: رَمِي ٱلْجَمَرَات, romanized: Ramī al-Jamarāt, lit. 'Stoning of the Place of Pebbles').[6][7][8]
