أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ أنبأ أَبُو بَكْرٍ أَحْمَدُ بْنُ جَعْفَرٍ ثنا عَبْدُ اللهِ بْنُ أَحْمَدَ بْنِ حَنْبَلٍ حَدَّثَنِي أَبِي ثنا الْحَسَنُ بْنُ مُوسَى ثنا عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللهِ بْنِ دِينَارٍ عَنْ زَيْدِ بْنِ أَسْلَمَ عَنْ عَطَاءِ بْنِ يَسَارٍ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللهِ ﷺ يُصَلُّونَ لَكُمْ فَإِنْ أَصَابُوا فَلَكُمْ وَلَهُمْ وَإِنْ أَخْطَئُوا فَلَكُمْ وَعَلَيْهِمْ
English Translation
The Shaykh (al-Bayhaqi) said: The meaning of the imam being a guarantor is that he takes responsibility for the prayer of those behind him. His prayer encompasses their prayer, and when he errs in something from it, the blame is upon him and not upon them, if they themselves did not err.
