(a) Sayyiduna Abu Hurayrah (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) saying: "When the imam says Amin, then you say Amin, for the angels also say Amin. Whoever's Amin coincides with the Amin of the angels, his previous sins will be forgiven."
(b) Ibn Shihab (may Allah have mercy on him) said: The Messenger of Allah (peace and blessings be upon him) used to say Amin in the prayer.
