Masjid al-Mashar is a mosque located in the holy city of Muzdalifah, which is located between Mina and Arafat in Saudi Arabia. It is one of the important landmarks of the Hajj pilgrimage, and is also known as the Mosque of Repose, because it is the place where pilgrims rest during the Hajj.
On the night of the 9th day of the Islamic month of Dhul Hijjah, after completing the stoning of the devil ritual in Mina, pilgrims spend the night in Muzdalifah and offer Maghrib and Isha prayers at Masjid al-Mashar. This is also the place where pilgrims gather pebbles for the stoning of the devil ritual on the following day.
Masjid al-Mashar is a simple and humble structure, with a capacity of accommodating up to 30,000 worshippers at a time. The mosque is surrounded by hills and is located in a remote area, which adds to its spiritual significance for pilgrims.
