Chapter: Saying of Amin aloud by the followers
Narrated Abu Huraira:
Allah's Messenger (ﷺ) said, "Say Amen when the Imam says 'Ghairi l-maghdubi `alaihim wala d-daalleen' (not the path of those who earn Your Anger (such as Jews) nor of those who go astray (such as Christians)); all the past sins of the person whose saying (of Amin) coincides with that of the angels, will be forgiven".
