وَحَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ، حَدَّثَنَا أَبِي، حَدَّثَنَا مُحَمَّدُ بْنُ عَمْرٍو اللَّيْثِيُّ، عَنْ عُمَرَ بْنِ مُسْلِمِ بْنِ عَمَّارِ بْنِ أُكَيْمَةَ اللَّيْثِيِّ، قَالَ سَمِعْتُ سَعِيدَ بْنَ الْمُسَيَّبِ، يَقُولُ سَمِعْتُ أُمَّ سَلَمَةَ، زَوْجَ النَّبِيِّ صلى الله عليه وسلم تَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ كَانَ لَهُ ذِبْحٌ يَذْبَحُهُ فَإِذَا أُهِلَّ هِلاَلُ ذِي الْحِجَّةِ فَلاَ يَأْخُذَنَّ مِنْ شَعْرِهِ وَلاَ مِنْ أَظْفَارِهِ شَيْئًا حَتَّى يُضَحِّيَ " .
