Muwatta Malik #194
Prayer
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ سُمَىٍّ، مَوْلَى أَبِي بَكْرٍ عَنْ أَبِي صَالِحٍ السَّمَّانِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِذَا قَالَ الإِمَامُ {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلاَ الضَّالِّينَ} فَقُولُوا آمِينَ فَإِنَّهُ مَنْ وَافَقَ قَوْلُهُ قَوْلَ الْمَلاَئِكَةِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ " .
Yahya related to me from Malik from Sumayy, the mawla of Abu
Bakr, from Abu Salih as Samman, from Abu Hurayra that the Messenger of
Allah, may Allah bless him and grant him peace, said, "When the imam
has said, 'not of those with whom You are angry nor of those who are
in error,' say 'Amin', for the previous wrong actions of the one whose
utterance coincides with that of the angels, are forgiven him."
