حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ زِيَادِ بْنِ أَنْعُمَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ رَافِعٍ، وَبَكْرِ بْنِ سَوَادَةَ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِذَا قَضَى الإِمَامُ الصَّلاَةَ وَقَعَدَ فَأَحْدَثَ قَبْلَ أَنْ يَتَكَلَّمَ فَقَدْ تَمَّتْ صَلاَتُهُ وَمَنْ كَانَ خَلْفَهُ مِمَّنْ أَتَمَّ الصَّلاَةَ " .
