What was revealed to Allah's Prophet (saw) that caused the people to turn their faces towards the Ka`ba?
 Narrated `Abdullah bin `Umar:                     While the people were at Quba offering the morning prayer, suddenly a person came to them saying, "Tonight Divine Inspiration has been revealed to Allah's Apostle and he has been ordered to face the Ka`ba (in prayers): therefore you people should face it." There faces were towards Sham, so they turned their faces towards the Ka`ba (at Mecca).
