(208) باب مَنْ صَلَّى لِغَيْرِ الْقِبْلَةِ ثُمَّ عَلِمَ
Anas said:
The Prophet (ﷺ) and his Companions used to pray in the direction of Jerusalem. When the following verse was revealed: " So turn thy face towards the inviolable mosque"; and Ye (O Muslims), wheresoever ye may be, turn your face towards it"(ii. 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.
