Yahya ibn Yahya narrated to us, saying: I recited to Malik, from Sumayy, from Abu Salih, from Abu Hurayrah, that the Messenger of Allah, peace and blessings be upon him, said: "When the imam says, 'Allah hears those who praise Him,' then say, 'O Allah, our Lord, to You is the praise.' For whoever's saying coincides with the saying of the angels, his previous sins will be forgiven."
