[Machine] The Messenger of Allah ﷺ said, "When the reader says '[not the path] of those who have incurred Your anger, nor of those who have gone astray' [Surah Al-Fatihah, verse 7], and the one behind him says 'Ameen', and the saying of the people of the heavens 'Ameen' coincides, then his previous sins will be forgiven."
قَالَ رَسُولُ اللهِ ﷺ إِذَا قَالَ الْقَارِئُ {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ} [الفاتحة 7] فَقَالَ مَنْ خَلْفَهُ آمِينَ فَوَافَقَ ذَلِكَ قَوْلَ أَهْلِ السَّمَاءِ آمِينَ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ
