"Whoever sees the new crescent of Dhul-Hijjah and wants to offer a sacrifice, let him not remove any of his hair or nails until he has offered the sacrifice." (Using translation from Nasāʾī 4361)  

عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ رَأَى هِلَالَ ذِي الْحِجَّةِ فَأَرَادَ أَنْ يُضَحِّيَ فَلَا يَأْخُذُ مِنْ شَعْرِهِ وَلَا مِنْ أَظْفَارِهِ حَتَّى يُضَحِّيَ»  

[Machine] Um Salama, the wife of the Prophet Muhammad ﷺ , informed him that the Messenger of Allah ﷺ said, "Whoever intends to offer a sacrifice (on the day of Eid), let him not remove anything from his nails or hair in the first ten days of Dhul-Hijjah." Abu Abdur Rahman Amr ibn Muslim ibn Ammar ibn Ukaimeh, who was also known as Umar or Amr, narrated this Hadith. He was a resident of Medina.  

أَنَّ أُمَّ سَلَمَةَ زَوْجَ النَّبِيِّ ﷺ أَخْبَرَتْهُ أَنَّ رَسُولَ اللهِ ﷺ قَالَ «مَنْ أَرَادَ أَنْ يُضَحِّيَ فَلَا يَقْلِمْ مِنْ أَظْفَارِهِ وَلَا يَحْلِقْ شَيْئًا مِنْ شَعْرِهِ فِي الْعَشْرِ الْأَوَّلِ مِنْ ذِي الْحِجَّةِ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ عَمْرُو بْنُ مُسْلِمِ بْنِ عَمَّارِ بْنِ أُكَيْمَةَ وَقَدِ اخْتُلِفَ فِي اسْمِهِ فَقِيلَ عُمَرُ وَقِيلَ عَمْرٌو وَهُوَ مَدَنِيٌّ  

"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?" (Using translation from Nasāʾī 4363)   

«مَنْ أَرَادَ الْثَّجَّ فَدَخَلَتْ أَيَّامُ الْعَشْرِ فَلَا يَأْخُذُ مِنْ شَعْرِهِ وَلَا أَظْفَارِهِ» فَذَكَرْتُهُ لِعِكْرِمَةَ فَقَالَ أَلَا يَعْتَزِلُ النِّسَاءَ وَالطِّيبَ  

"when the (first) ten (days of Dhul-Jijjah) begin, and one of you wants to offer a sacrifice, let him not remove anything from his hair or skin." (Using translation from Nasāʾī 4364)  

أَنَّ النَّبِيَّ ﷺ قَالَ «إِذَا دَخَلَتِ الْعَشْرُ فَأَرَادَ أَحَدُكُمْ أَنْ يُضَحِّيَ فَلَا يَمَسَّ مِنْ شَعْرِهِ وَلَا مِنْ بَشَرِهِ شَيْئًا»
