Grade: Sahih (authentic) according to Muslim

Al-Nawawi said, “The scholars disagreed regarding one who enters the ten days of Dhul Hijjah and he intends to sacrifice. Sa’id ibn al-Musayyib, Rabi’ah, Ahmad, Ishaq, Dawud, and some of the companions of Al-Shafi’i said it is forbidden for him to take anything off his hair or nails until he completes the sacrifice in its time. Al-Shafi’i and his companions said it is mildly discouraged but is not forbidden. Abu Hanifa said it is not discouraged. Malik said in one narration that it is not discouraged, in another narration that it is discouraged, and in another narration that it is forbidden in voluntary sacrifices besides the obligation.”

عَنْ أُمِّ سَلَمَةَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِذَا دَخَلَتْ الْعَشْرُ وَأَرَادَ أَحَدُكُمْ أَنْ يُضَحِّيَ فَلَا يَمَسَّ مِنْ شَعَرِهِ وَبَشَرِهِ شَيْئًا

1977 صحيح مسلم كتاب الأضاحي باب نهي من دخل عليه عشر ذي الحجة وهو مريد التضحية أن يأخذ من شعره أو أظفاره شيئا

قال النووي وَاخْتَلَفَ الْعُلَمَاءُ فِيمَنْ دَخَلَتْ عَلَيْهِ عَشْرُ ذِي الْحِجَّةِ وَأَرَادَ أَنْ يُضَحِّيَ فَقَالَ سَعِيدُ بْنُ الْمُسَيِّبِ وَرَبِيعَةُ وَأَحْمَدُ وَإِسْحَاقُ وَدَاوُدُ وَبَعْضُ أَصْحَابِ الشَّافِعِيِّ إِنَّهُ يَحْرُمُ عَلَيْهِ أَخْذُ شَيْءٍ مِنْ شَعْرِهِ وَأَظْفَارِهِ حَتَّى يُضَحِّيَ فِي وَقْتِ الْأُضْحِيَّةِ وَقَالَ الشَّافِعِيُّ وَأَصْحَابُهُ هُوَ مَكْرُوهٌ كَرَاهَةَ تَنْزِيهٍ وَلَيْسَ بِحَرَامٍ وَقَالَ أَبُو حَنِيفَةَ لَا يُكْرَهُ وَقَالَ مَالِكٌ فِي رِوَايَةٍ لَا يُكْرَهُ وَفِي رِوَايَةٍ يُكْرَهُ وَفِي رِوَايَةٍ يَحْرُمُ فِي التَّطَوُّعِ دُونَ الْوَاجِبِ
