’You must turn your face to the Masjid al-Haram (the Sacred Masjid). Wherever you are you must turn your faces toward it.’ (2:144) Your eyes must be cast down instead of being raised to the sky and your eye must remain before your face on the place for your Sujud (prostrations).’” حسن - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (5/78))
