أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ قَالَ حَدَّثَنَا سُفْيَانُ عَنْ الزُّهْرِيِّ عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ عَنْ أَبِي هُرَيْرَةَ عَنْ النَّبِيِّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِذَا أَمَّنَ الْقَارِئُ فَأَمِّنُوا فَإِنَّ الْمَلَائِکَةَ تُؤَمِّنُ فَمَنْ وَافَقَ تَأْمِينُهُ تَأْمِينَ الْمَلَائِکَةِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ
سنن نسائی · Hadith 931
It was narrated from Abu Hurairah that the Prophet ~ said: “When the reciter says Amin, then say: ‘Amin’ too, for the angels say Amin and if a person’s Amin coincides with the Amin of the angels, his previous sins will be forgiven.”(Sahih).
