Al-Sahla Mosque (Arabic: مسجد السهلة), also known as al-Suhayl Mosque ( مسجد السهیل), Banū Ẓafar Mosque ( مسجد بنی ظفر) and ʿAbd al-Qays Mosque ( مسجد عبدالقیس), 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 (a), the twelfth Shiite Imam. There is a place (so-called "maqam") in the mosque attributed to Imam al-Mahdi (a), and on some accounts, this mosque is where Imam al-Mahdi (a) will live after his reappearance. In the Shiite culture, al-Sahla Mosque one the 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 (a), Imam al-Sadiq (a), Ibrahim (a), Idris (a) and Khidr (a).
Al-Sahla Mosque was built by the Banu Zafar tribe, a clan of Ansar. Imam 'Ali (a) allegedly took the Banu Zafar Mosque to be equivalent to the Kufa Mosque. The mosque is called al-Suhayl, because its architect was a person called al-Suhayl, and it is called 'Abd al-Qays, because 'Abd al-Qays was the tribe in whose area of residence the mosque was constructed, and it is called Banu Zafar, since they are a clan of the 'Abd al-Qays tribe.
Ibn al-Faqih quoted Imam 'Ali (a) as saying that: "there are four sacred places in Kufa in which four mosques have been constructed." He was asked: "what are those mosques?" He replied: "one of them is the Zafar or al-Sahla Mosque".
Al-Sahla Mosque is located in eastern Najaf, that is the old city of Kufa. It is located 10 kilometers northwest of Imam 'Ali's (a) Holy Shrine with 37 degrees of angle, and 2 kilometers northwest of the Kufa Mosque with 53 degrees of angle.
The mosque was a home and a place of worship for many prophets, such as Ibrahim (a), Idris (a), Khidr (a) and some Shiite Imams (a), such as Imam al-Sajjad (a) and Imam al-Sadiq (a). According to a hadith from Imam al-Sadiq (a), Imam al-Mahdi (a) will reside in this mosque after his reappearance.
According to a hadith from Imam al-Sadiq (a), al-Suhayl Mosque was a home for Ibrahim (a) and Idris (a) 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 (a), there was a house in this place where the prophet Idris (a) used to sew. And this is the place from which Ibrahim (a) 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 (a) and it is where the prophet Moses (a) met Khidr (a). If an anxious person goes there, God will comfort him or her and solves their problems.
According to a hadith from Imam al-Baqir (a), 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 (a), if a person says two rak'as of prayer in al-Sahla Mosque, God will add two years to his or her life.
There are different mihrabs in different parts of the mosque's courtyard attributed to different prophets and Imams (a). These are called "maqam" (stance). They are as follows:
