[Machine] The Messenger of Allah ﷺ said, "When the reciter says, 'not (the way) of those who have evoked (Your) anger, nor of those who have gone astray.' [Al-Fatiha 7], and those behind him say 'Ameen,' the angels in the heaven align with it and his previous sins are forgiven."  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا قَالَ الْقَارِئُ {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ} [الفاتحة 7] فَقَالَ مَنْ خَلْفَهُ آمِينَ فَوَافَقَ ذَلِكَ أَهْلَ السَّمَاءِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ  

"The Messenger of Allah ﷺ said: 'When the Imam says: Not (the way) of those who earned Your anger, nor of those who went astray, say: 'Amin' for the angels say Amin and the Imam says Amin, and if a person's Amin coincides with the Amin of the angels, his previous sins will be forgiven.'" (Using translation from Nasāʾī 927)  

أَنَّ نَبِيَّ اللَّهِ ﷺ قَالَ إِذَا قَالَ الْإِمَامُ {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ} [الفاتحة 7] فَقُولُوا آمِينَ فَإِنَّ الْمَلَائِكَةَ تَقُولُ آمِينَ وَإِنَّ الْإِمَامَ يَقُولُ آمِينَ فَمَنْ وَافَقَ تَأْمِينُهُ تَأْمِينَ الْمَلَائِكَةِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ
