حَدَّثَنَا الْقَعْنَبِيُّ عَنْ مَالِکٍ عَنْ ابْنِ شِهَابٍ عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ وَأَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ أَنَّهُمَا أَخْبَرَاهُ عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِذَا أَمَّنَ الْإِمَامُ فَأَمِّنُوا فَإِنَّهُ مَنْ وَافَقَ تَأْمِينُهُ تَأْمِينَ الْمَلَائِکَةِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ قَالَ ابْنُ شِهَابٍ وَکَانَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ آمِينَ
سنن ابودوٗد · Hadith 936
Abu Hurairah reported the Messenger of Allah ﷺ as saying; When the Imam says Amin, say Amin, for if anyone’s utterance of Amin synchronnises with that of the angles, he will be forgiven his past sins. Ibn shihab (al Zuhrl) said; The Messenger of Allah ﷺ used to say Amin (At the end of the Fatihah)
