البيهقي:٥٧٣٧أَخْبَرَنَا أَبُو زَكَرِيَّا بْنُ أَبِي إِسْحَاقَ الْمُزَكِّي أنبأ أَبُو عَبْدِ اللهِ مُحَمَّدُ بْنُ يَعْقُوبَ ثنا أَبُو أَحْمَدَ مُحَمَّدُ بْنُ عَبْدِ الْوَهَّابِ ثنا جَعْفَرُ بْنُ عَوْنٍ أنبأ يَحْيَى بْنُ سَعِيدٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ قَالَ مَنْ أَدْرَكَ رَكْعَةً مِنَ الْجُمُعَةِ فَقَدْ أَدْرَكَهَا إِلَّا
