Masjid Juhaina was established as a mosque for the tribes of Juhaina and Billi by the Prophet (ﷺ). It is on the southern end of Mount Sila.
- Ibn Shaiba narrates from Maaz Ibn Abdullah Ibn Abi Mariam Ajjahani and others that the Prophet (peace and blessings of Allah be upon him) prayed in Juhaina mosque.
- Jabir Ibn Osama Ajjahani says, ”I met the Prophet (peace and blessings of Allah be upon him) with his companions in the market. I asked, ”Where were you going with the Prophet (peace and blessings of Allah be upon him)?” They said, ”To set a mosque for your people”. I came back and saw that the Prophet (peace and blessings of Allah be upon him) set a mosque for my people and inserted a wooden stick in to refer to the Qiblah direction”. This happened in the spot where the mosque stands today.
