He (the Imam) said, ‘If he stands up there is no al-Qiblah (al-Ka‘bah) for him; however, he lies down on his back and opens his eyes to the sky and keeps in his heart al-Qiblah which is in the heaven, al-Bayt al-Ma‘mur, does the recitation and for Ruku‘ (bowing down on one’s knees) closes his eyes.

When intending to raise his head from Ruku‘ opens his eyes and for Sujud (prostrations) he does the same.’” ضعيف - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (5/297))
