All rights reserved.Baghdad has been a city where there have been intense sectarian fights, which became much more apparent in the late third/ninth and early fourth/tenth centuries. On the one side of these fights were Shī'ites and on the other Sunnīs. The intensity of fights increased from time to time and the disputes evolved into actual interventions in religious centers. The Barāthā Mosque, which has a special place in the Shī'ite faith and culture, is one of these centers. In this article, an apocalyptic hadith regarding the Barāthā Mosque, which caused serious tensions between the Shī'ites and Sunnīs in Baghdad in the late third/ninth and early fourth/tenth centuries, is analyzed. In this context, the story of this famous mosque, which caused serious fights between the Shī'ites and Sunnīs, and therefore, was subjected to political and military interventions, had changed hands at times, was demolished and destroyed by the state, and reconstructed by the state, has been evaluated within the context of the history-hadith relationship and an approximate date for hadith's circulation is suggested.
