عَنْ أُمِّ سَلَمَةَ رَضِيَ اللَّهُ عَنْهَا مِنْ طَرِيقٍ ثَالِثٍ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ قَالَ مَنْ أَرَادَ أَنْ يَنْحَرَ فِي هِلَالِ ذِي الْحِجَّةِ فَلَا يَأْخُذْ مِنْ شَعْرِهِ وَأَظْفَارِهِ
(Third chain) The Noble Prophet, peace and blessings be upon him and his family, said: Whoever intends to offer a sacrifice in the month of Dhu al-Hijjah should not touch his hair or nails.
