أَخْبَرَنَا مُحَمَّدُ بْنُ أَحْمَدَ ، حَدَّثَنَا سُفْيَانُ ، حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ حُمَيْدٍ ، عَنْ سَعِيدِ بْنِ الْمُسَيِّبِ ، عَنْ أُمِّ سَلَمَةَ ، عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ :" إِذَا دَخَلَتْ الْعَشْرُ، وَأَرَادَ أَحَدُكُمْ أَنْ يُضَحِّيَ، فَلَا يَمَسَّ مِنْ شَعْرِهِ وَلَا أَظْفَارِهِ شَيْئًا "
