أَخْبَرَنَا عَلِيُّ بْنُ عُثْمَانَ النُّفَيْلِيُّ، قَالَ حَدَّثَنَا سَعِيدُ بْنُ عِيسَى، قَالَ حَدَّثَنَا الْمُفَضَّلُ بْنُ فَضَالَةَ، قَالَ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنِي نَافِعٌ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَحَرَ يَوْمَ الأَضْحَى بِالْمَدِينَةِ - قَالَ - وَقَدْ كَانَ إِذَا لَمْ يَنْحَرْ يَذْبَحُ بِالْمُصَلَّى .
