The Prophet (ﷺ) and his Companions used to pray in the direction of Jerusalem. When the following verse was revealed: " So turn your face towards the inviolable mosque" ; and Ye (O Muslims), wheresoever ye may be, turn your face towards it" (2:144), a man passed by the people of Banu Salamah. He called them while they were bowing in the morning prayer facing Jerusalem: Lo, the qiblah (direction of prayer) has been changed towards the ka'bah. He called them twice. So they turned their faces towards the Ka'bah while they were bowing.
