The Book of Prayers (Kitab Al-Salat)
Muslim :: Book 4 : Hadith 751
Abu Sufyan reported it on the authority of Jabir that he had heard the Apostle of Allah (may peace be upon him) say: When Satan hears the call to prayer, he runs away to a distance like that of Rauha. Sulaimin said: I asked him about Rauha. He replied: It is at a distance of thirty-six miles from Medina.
