حَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، حَدَّثَنِي ابْنُ وَهْبٍ، أَخْبَرَنِي عَمْرٌو، أَنَّ أَبَا يُونُسَ، حَدَّثَهُ عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ إِذَا قَالَ أَحَدُكُمْ فِي الصَّلاَةِ آمِينَ ‏.‏ وَالْمَلاَئِكَةُ فِي السَّمَاءِ آمِينَ ‏.‏ فَوَافَقَ إِحْدَاهُمَا الأُخْرَى غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ ‏"‏ ‏.‏
