Masjid al Fash is a small mosque in Madinah adjacent to Mount Uhud on the side of the Qiblah, on the right of the one going to the valley of Al-Jarar where the mortar is located, under the cave which some narrations say the Prophet (صلى الله عليه وسلم), entered on the day of Uhud and prayed there.
It is square in shape, its length from north to south is 3.8 m, and its width from east to west is 3.2 m. It was dilapidated, and only small parts of the southern wall remain, with a height of about 2.1 m and a thickness of 1.1 m. The hollow mihrab is clearly visible in its middle, with a height of 1.8 m. It is noted that the thickness of this wall is greater than the thickness of the other walls, which reached a thickness of 75 cm.
This is due to the presence of the hollow mihrab inside the wall. It is estimated that it was built during the time of Umar bin Abdul Aziz, who governed Madinah during the Umayyad Caliphate.
It has now become a historical site that many travellers to Madinah go to visit, after the Masjid and its surrounding area were recently restored.
