Among the most important historic mosques in Makkah, located near the Grand Mosque. Its construction dates back to the early 9th century CE. Its name is derived from the place where the Prophet met with the jinn at night, and where Sūrat al-Jinn was revealed. Almighty God says in the Qurʾān: Say, “It has been revealed to me that a group of the jinn listened and said, ‘Indeed, we have heard a wondrous Qurʾān’” [Sūrat al-Jinn: verse 1]. It is also known as the Mosque of the Guards [Masjid al-Ḥaras], as it was the last point on the northeastern side of the Sacred Precinct used as a meeting and gathering place by the guards who kept the peace in Makkah. Another name for it is the Mosque of the Pledge [Masjid al-Bayʿa] because the jinn pledged their allegiance to the Prophet at this site. It is one of the mosques that received special attention and care from King Abdulaziz Al Saud. The structure of this mosque has been recently renovated.
