Arabic (Original)
حَدَّثَنَا يَزِيدُ قَالَ أَخْبَرَنَا مُحَمَّدٌ عَنْ أَبِي سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا قَالَ الْقَارِئُ { غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ } فَقَالَ مَنْ خَلْفَهُ آمِينَ فَوَافَقَ ذَلِكَ قَوْلَ أَهْلِ السَّمَاءِ آمِينَ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ.
English Translation
Yazid told us, he said: Muhammad informed us, from Abu Salamah, from Abu Hurayrah, who said: The Messenger of Allah, peace and blessings be upon him, said: "When the reciter says, 'not of those who have evoked [Your] anger, nor of those who are astray,' and those behind him say 'Amin,' and that coincides with the saying of the inhabitants of heaven, 'Amin,' his past sins are forgiven."
