When the Messenger of Allah ﷺ recited the verse "Not of those with whom Thou art angry, nor of those who go astray," he would say Amin so loudly that those near him in the first row would hear it.
كَانَ رَسُولُ اللَّهِ ﷺ إِذَا تَلاَ { غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلاَ الضَّالِّينَ } قَالَ آمِينَ حَتَّى يَسْمَعَ مَنْ يَلِيهِ مِنَ الصَّفِّ الأَوَّلِ
“The people stopped saying Amin, but when the Messenger of Allah ﷺ said ‘Not (the way) of those who earned Your Anger, nor of those who went astray’[1:7] he would say Amin, until the people in the first row could hear it, and the mosque would shake with it.
تَرَكَ النَّاسُ التَّأْمِينَ وَكَانَ رَسُولُ اللَّهِ ﷺ إِذَا قَالَ {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلاَ الضَّالِّينَ} قَالَ آمِينَ حَتَّى يَسْمَعَهَا أَهْلُ الصَّفِّ الأَوَّلِ فَيَرْتَجُّ بِهَا الْمَسْجِدُ
"كانَ رَسُولُ الله ﷺ إذَا قَالَ: غَيْرِ المَغْضُوبِ عَلَيْهِم وَلَا الضَّالِّين قَالَ: آمين حَتَّى يُسْمِعَهَا".
