It is narrated from Sayyiduna Abu Ayyash Zarqi that once the Prophet (peace and blessings be upon him) led the prayer of fear (Salat al-Khawf). At that time, the polytheists were positioned between us and the Qiblah. The Prophet (peace and blessings be upon him) performed such a prayer twice: once at Usfan and once in a region of Banu Sulaym.
