وَعَنْ أُمِّ سَلَمَةَ قَالَتْ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا دَخَلَ الْعَشْرُ وَأَرَادَ بَعْضُكُمْ أَنْ يُضَحِّيَ فَلَا يَمَسَّ مِنْ شَعْرِهِ وَبَشَرِهِ شَيْئًا» وَفِي رِوَايَةٍ «فَلَا يَأْخُذَنَّ شَعْرًا وَلَا يَقْلِمَنَّ ظُفْرًا» وَفِي رِوَايَةٍ «مَنْ رَأَى هِلَالَ ذِي الْحِجَّةِ وَأَرَادَ أَنْ يُضَحِّيَ فَلَا يَأْخُذْ مِنْ شَعْرِهِ وَلَا مِنْ أَظْفَارِهِ» . رَوَاهُ مُسلم
