"Ibn Al-Musayyab told me that Umm Salamah, the wife of the Prophet told him that the Messenger of Allah said: 'Whoever wants to offer a sacrifice, let him not remove anything from his nails or cut his hair for the first ten days Dhul-Jijjah."' (Using translation from Nasāʾī 4362)   

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ «مَنْ أَرَادَ أَنْ يُضَحِّيَ فَلَا يُقَلِّمْ أَظْفَارَهُ وَلَا يَحْلِقْ شَيْئًا مِنْ شَعْرِهِ فِي الْعَشْرِ الْأُوَلِ مِنْ ذِي الْحِجَّةِ»  

"Ibn Al-Musayyab told me that Umm Salamah, the wife of the Prophet told him that the Messenger of Allah said: 'Whoever wants to offer a sacrifice, let him not remove anything from his nails or cut his hair for the first ten days Dhul-Jijjah."' (Using translation from Nasāʾī 4362)   

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «مَنْ أَرَادَ أَنْ يُضَحِّيَ فَلَا يُقَلِّمْ أَظْفَارَهُ وَلَا يَحْلِقْ شَيْئًا مِنْ شَعْرِهِ فِي الْعَشْرِ مِنْ ذِي الْحِجَّةِ»  

[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
