Another name of this place is "Jam". Because pilgrims gather there. This point is the same as Mushar al-Haram mentioned in the Qur'an.
Muzdalifa, with an area of about 63.9 square kilometers, is located between Mina and Arafat, which is limited to Wadi Mazameen and Hayaz. Standing in Muzdalifah on the 10th night of the month of Dhi-Hijjah is one of the obligations of Hajj.
