Hadith 4363
Chapter 1: The One Who Wishes To Offer A Sacrifice Should Not Remove Any Of His Hair - كتاب الضحايا
أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ أَنْبَأَنَا شَرِيكٌ، عَنْ عُثْمَانَ الأَحْلاَفِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، قَالَ مَنْ أَرَادَ أَنْ يُضَحِّيَ، فَدَخَلَتْ أَيَّامُ الْعَشْرِ فَلاَ يَأْخُذْ مِنْ شَعْرِهِ وَلاَ أَظْفَارِهِ . فَذَكَرْتُهُ لِعِكْرِمَةَ فَقَالَ أَلاَ يَعْتَزِلُ النِّسَاءَ وَالطِّيبَ .
It was narrated that Sa'eed bin Al-Musayyab said:
"Whoever wants to offer a sacrifice when dhul-Hijjah begins, let him not remove anything from his hair or nails." I (the narrator) mentioned that to 'Ikrimah, and he said: "Should he not also keep away from women and perfume?"
