Q: There is a person with weak hearing who often does not hear the imaam. Should they pray by themselves or recite for themselves behind the imaam?
A: They should pray with the imaam and follow people by looking [at their actions]. It has been related that the prophet ﷺ would sometimes look out of the corner of his eye during the prayer, so if the congregation are in a situation where they must do so, it is permissible.
الجواب : يصلي مع الإمام ويتابع الناس بالنظر، وقد ورد أن النبي صلى الله عليه وسلم كان يلحظ في صلاته أحياناً فإن اضطر المأموم أن يلحظ [ أي ينظر بطرف عينه] فلا حرج.
