Sunan Abi Dawud, Hadith 934 ⓘ
Narrated AbuHurayrah: When the Messenger of Allah 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.
حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ، أَخْبَرَنَا صَفْوَانُ بْنُ عِيسَى، عَنْ بِشْرِ بْنِ رَافِعٍ، عَنْ أَبِي عَبْدِ اللَّهِ ابْنِ عَمِّ أَبِي هُرَيْرَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا تَلاَ { غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلاَ الضَّالِّينَ } قَالَ " آمِينَ " . حَتَّى يَسْمَعَ مَنْ يَلِيهِ مِنَ الصَّفِّ الأَوَّلِ .
