What was the instruction Allah (SWT) revealed to the Prophet Muhammad (saw) concerning the direction in which to face during prayer?
 Narrated Ibn `Umar:                     While some people were offering Fajr prayer in the Quba' mosque, some-one came and said, "Allah has revealed to the Prophet Qur'anic instructions that you should face the Ka`ba (while praying) so you too, should face it." Those people then turned towards the Ka`ba.
