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)."  

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 Sumayy, the mawla of Abu Bakr, from Abu Salih as Samman, from Abu Hurayra that the Messenger of Allah ﷺ 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."  

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  

Yahya related to me from Malik from Abu'z Zinad from al-Araj from Abu Hurayra that the Messenger of Allah ﷺ said, "When one of you says 'Amin' and the angels in the sky say 'Amin' so that one coincides with the other, his previous wrong actions are forgiven him."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا قَالَ أَحَدُكُمْ آمِينَ وَقَالَتِ الْمَلاَئِكَةُ فِي السَّمَاءِ آمِينَ فَوَافَقَتْ إِحْدَاهُمَا الأُخْرَى 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 ﷺ said, "When the imam says, 'Allah hears whoever praises Him,' say 'O Allah! Our Lord, praise be toYou, 'for the previous wrong actions done by the one whose utterance coincides with that of the angels are forgiven."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا قَالَ الإِمَامُ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَقُولُوا اللَّهُمَّ رَبَّنَا لَكَ الْحَمْدُ فَإِنَّهُ مَنْ وَافَقَ قَوْلُهُ قَوْلَ الْمَلاَئِكَةِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ
