[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
