Sayyiduna Jabir (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings be upon him) say: When Satan hears the call to prayer (adhan), he goes away until he reaches "Ruhā’." The narrator named Sulaiman says: I asked my teacher about "Ruhā’," and he replied: It is at a distance of 37 miles from Madinah Munawwarah.
