During the days of the battle of the harra[*] neither the call to prayer nor the declaration that the time for prayer had come was made for three days at the Prophet's Mosque. Sa'id b. al-Musayyib did not leave the mosque, and the only means by which he knew the time for prayer was a whinnying he heard coming from the Prophet's grave. *When the people of Medina rebelled against the Umayyad Caliph Yazid he sent an army under Muslim b. 'Uqba al-Murri towards the end of 63 A.H. The Medina troops were defeated in a battle known by the name given above. Darimi transmitted it.
