What did Allah's Apostle order to do after he revealed something to him at the night prayer at Quba (near Medina)?
 Narrated `Abdullah bin `Umar:                     While the people were offering the Fajr prayer at Quba' (near Medina), someone came to them and said: "It has been revealed to Allah's Apostle tonight, and he has been ordered to pray facing the Ka`ba." So turn your faces to the Ka`ba. Those people were facing Sham (Jerusalem) so they turned their faces towards Ka`ba (at Mecca).
