Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Hammad ibn ‘Isa from Hariz from Muhammad ibn Muslim who has said the following: “I once asked abu ‘Abd Allah (a.s.), about a man and a woman who lose their eyesight. Physicians say that they can treat them within a month or forty nights while they remain lying down on their back. Can they perform Salah (prayer) in this condition?

He (the Imam) gave permission saying, ‘(Permission is granted to) those who are compelled and they are not rebels and transgressors. It is not a sin on them. (2:168)’” صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (5/333))
