“From whencesoever Thou startest forth, turn Thy face in the direction of the sacred Mosque; that is indeed the truth from the Lord. And Allah is not unmindful of what ye do” (Qur'an 2:149–150).

“Qibla (or qiblah; Arabic: قبلة‎) is an Arabic word for the direction that should be faced when a Muslim prays during Salah, the Islamic practice of formal prayer, usually performed five times a day. Since 622 AD, that direction has been towards Kaaba (The Cube), a cube-shaped building in Mecca, Saudi Arabia, which is the most sacred site in Islam. Muslim mosques are aligned with qibla, Muslims are buried with their faces in the direction of the qibla, and the fact that all Muslims pray towards the Kaaba is traditionally considered to be a symbol of the unity of all Muslims worldwide,” (Wikipedia, Qibla).
