Sahih al-Bukhari
Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
The Statement of Allah: "...And We made the Qiblah (prayer direction towards Jerusalem) which you used to face, only to test those who followed the Messenger (Muhammad ) . . ." (V.2:143)
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 (ﷺ) 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.
