Al-Sahla Mosque, also known as al-Suhayl Mosque, Banu Zafar Mosque and Abd al-Qays Mosque, is one of the best-known Islamic mosques built in the 1st/7th century by some Arab tribes of Kufa, about two kilometers northwest of the Great Mosque of Kufa.

The mosque is one of the oldest mosques associated with Imam al-Mahdi (AS), the twelfth Shia Imam. There is a place, called “maqam”, in the mosque attributed to Imam al-Mahdi (AS), and on some accounts, this mosque is where Imam al-Mahdi (AS) will live after his reappearance. In the Shia culture, al-Sahla Mosque is one the most important mosques. In different parts of the mosque’s courtyard, some mihrabs are built and are called after religious leaders, such as maqams (stances) of Imam al-Sajjad (AS), Imam al-Sadiq (AS), Ibrahim (AS), Idris (AS) and Khidr (AS).

The mosque was a home and a place of worship for many prophets, such as Ibrahim (AS), Idris (AS), Khidr (AS) and some Shia Imams, including Imam al-Sajjad (AS) and Imam al-Sadiq (AS). According to a hadith from Imam al-Sadiq (AS), Imam al-Mahdi (AS) will reside in this mosque after his reappearance.

According to a hadith from Imam al-Sadiq (AS), al-Suhayl Mosque was a home for Ibrahim (AS) and Idris (AS) and it is the place where the Sur (trumpet) will be blown on Dooms Day. 70,000 people from around the mosque will go to the Heaven without any evaluation.

According to another hadith from Imam al-Sadiq (AS), there was a house in this place where the prophet Idris (AS) used to sew. And this is the place from which Ibrahim (AS) moved to Amalek. There is a rock in this place on which images of prophets are drawn, and some soil was taken from this mosque from which God created prophets. It is the place of the prophet Khidr (AS) and it is where the prophet Moses (AS) met Khidr (AS). If an anxious person goes there, God will comfort him or her and solves their problems.

According to a hadith from Imam al-Baqir (AS), God did not raise a prophet unless he said prayers in this mosque. Divine justice will appear in this place, and it is home to prophets, Imams and righteous persons. And according to a hadith from Imam al-Sajjad (AS), if a person says two rak’as of prayer in al-Sahla Mosque, God will add two years to his or her life.
