In which Mash'ar (sacred site) is Jabal Quzah (Mount Quzah) located?

Mount Quzah is a mountain in Al-Mash'ar Al-Haram, and the name may refer generally to Al-Mash'ar Al-Haram itself. It was located in Muzdalifah but was removed during the expansion of the holy sites, and a mosque was built in its place. Allah commanded Muslims to remember Him there after departing from Arafat, either by performing the Maghrib and Isha prayers together in delayed fashion, or by supplicating and reciting the talbiyah.
