Masjid Mashar al-Haram is a mosque situated in Muzdalifah which marks the area where the Prophet ﷺ supplicated during his Farewell Pilgrimage. It is located midway between Masjid al-Khayf in Mina and Masjid al-Namirah in Arafat.

Masjid Al-Mashar Al-Haram covers a land of 90 metres in length (from east to west) and 56 metres in width. It is believed that Masjid Al-Mashar Al-Haram can easily accommodate more than 12,000 worshippers at one time.

Jabir (RA) narrated that during the Farewell Hajj, Prophet Muhammad (PBUH) stayed in Muzdalifah overnight. The following day, the Messenger (PBUH) of Allah SWT woke up to perform the Fajr Prayer. He (PBUH) mounted on his she-camel and rode towards Mashar Al-Haram, where Prophet Muhammad (PBUH) faced the Qibla, prayed Salah, and made dua, proclaiming the Oneness and Greatness of Allah SWT.

Muzdalifah is located in the southeastern region of Mina. It is an open area where pilgrims arrive after the sunset of the 9^th Dhul-Hijjah from Arafat and spend the night here. Muzdalifah is four kilometres long and covers an area of 12.25 square kilometres. To be exact, Muzdalifah stretches from the land of Mashar to the mountains of Mazamayn.

During Hajjat ul-Wida, it was Muzdalifah where Prophet Muhammad (PBUH) performed the Maghrib and Isha prayers and stayed for the night. The Messenger (PBUH) said, “Although I am staying here, you may stay anywhere throughout Muzdalifah.” (Muslim)

In addition to spending the night at Muzdalifah praying, pilgrims are also instructed to collect pebbles for pelting the Jamarat from here. It is believed that a stay at Muzdalifah can change a Muslim’s life and heart for good.
