The Prophet ﷺ said, "Say Amin" when the Imam says it and if the Amin of any one of you coincides with that of the angels then all his past sins will be forgiven." Ibn Shihab said, "Messenger of Allah ﷺ used to Say "Amin."  

أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا أَمَّنَ الإِمَامُ فَأَمِّنُوا فَإِنَّهُ مَنْ وَافَقَ تَأْمِينُهُ تَأْمِينَ الْمَلاَئِكَةِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ وَقَالَ ابْنُ شِهَابٍ وَكَانَ رَسُولُ اللَّهِ ﷺ يَقُولُ آمِينَ  

Messenger of Allah ﷺ said, "Say Amen when the Imam says 'Ghairi l-maghdubi ʿalaihim 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".  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا قَالَ الإِمَامُ {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلاَ الضَّالِّينَ} فَقُولُوا آمِينَ فَإِنَّهُ مَنْ وَافَقَ قَوْلُهُ قَوْلَ الْمَلاَئِكَةِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ  

Messenger of Allah ﷺ said, "When the Imam says: 'Ghair-il-Maghdubi ʿalaihim Walad-Dallin (i.e. not the path of those who earn Your Anger, nor the path of those who went astray (1.7)), then you must say, 'Ameen', for if one's utterance of 'Ameen' coincides with that of the angels, then his past sins will be forgiven."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا قَالَ الإِمَامُ {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلاَ الضَّالِّينَ} فَقُولُوا آمِينَ فَمَنْ وَافَقَ قَوْلُهُ قَوْلَ الْمَلاَئِكَةِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ  

The Prophet ﷺ said, "When the Imam says 'Amin', then you should all say 'Amin', for the angels say 'Amin' at that time, and he whose 'Amin' coincides with the 'Amin' of the angels, all his past sins will be forgiven."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا أَمَّنَ الْقَارِئُ فَأَمِّنُوا فَإِنَّ الْمَلاَئِكَةَ تُؤَمِّنُ فَمَنْ وَافَقَ تَأْمِينُهُ تَأْمِينَ الْمَلاَئِكَةِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ

"The Messenger of Allah ﷺ said: 'When the reciter says Amin, then say: "Amin" too, for the angels say Amin and if a person's Amin coincides with the Amin of the angels, Allah will forgive his previous sins"  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَمَّنَ الْقَارِئُ فَأَمِّنُوا فَإِنَّ الْمَلاَئِكَةَ تُؤَمِّنُ فَمَنْ وَافَقَ تَأْمِينُهُ تَأْمِينَ الْمَلاَئِكَةِ غَفَرَ اللَّهُ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ

Abu Hurairah reported the prophet ﷺ as saying; when the imam recites “ not of those with whom thou art angry, nor of those who go astray” (surah al-fatihah,verse 7) say Amin, for if one’s words (utterance of amin) synchronise with those of the angles, he will be forgiven his past sins.

Abu Hurairah reported the Messenger of Allah (May peace be upon him) as saying; When the Imam says Amin, say Amin, for if anyone’s utterance of Amin synchronnises with that of the angles, he will be forgiven his past sins.

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا أَمَّنَ الإِمَامُ فَأَمِّنُوا فَإِنَّهُ مَنْ وَافَقَ تَأْمِينُهُ تَأْمِينَ الْمَلاَئِكَةِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ قَالَ ابْنُ شِهَابٍ وَكَانَ رَسُولُ اللَّهِ ﷺ يَقُولُ آمِينَ

Yahya related to me from Malik from Ibn Shihab that Sa'id ibn al- Musayyab and Abu Salama ibn Abd ar-Rahman told him from Abu Hurayra that the Messenger of Allah ﷺ said, "When the imam says 'Amin', say 'Amin', for the one whose 'Amin' coincides with the 'Amin' of the angels - his previous wrong actions are forgiven him." Ibn Shihab said, "The Messenger of Allah ﷺ used to say 'Aameen' (extending it)."
