Abu Abdur-Rahman Abdullah bin Ahmad said, my father, and Muhammad bin Amr, meaning Ibn Al-Qamah reported from Umar bin Muslim bin Ammar bin Ukaimah that he said: "If he said what he said, then my father said in the hadith: Whoever intends to offer a sacrifice, let him not clip his nails or trim his hair from the first ten days of Dhul-Hijjah."  

أحمد:٢٦٥٧١حَدَّثَنَا حَسَنٌ قَالَ حَدَّثَنَا ابْنُ لَهِيعَةَ قَالَ حَدَّثَنِي سَعِيدُ بْنُ أَبِي هِلَالٍ عَنْ عَمْرِو بْنِ مُسْلِمٍ الْجُنْدُعِيِّ أَنَّهُ قَالَ أَخْبَرَنِي ابْنُ الْمُسَيِّبِ

أَنَّ أُمَّ سَلَمَةَ زَوْجَ النَّبِيِّ ﷺ أَخْبَرَتْهُ عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ قَالَ قَالَ أَبُو عَبْدِ الرَّحْمَنِ عَبْدُ اللهِ بْنُ أَحْمَدَ قَالَ أَبِي وقَالَ مُحَمَّدُ بْنُ عَمْرٍو يَعْنِي ابْنَ عَلْقَمَةَ عَنْ عُمَرَ بْنِ مُسْلِمِ بْنِ عَمَّارِ بْنِ أُكَيْمَةَ أَنَّهُ قَالَ إِنْ كَانَ قَالَهُ كَذَا قَالَ أَبِي فِي الْحَدِيثِ مَنْ أَرَادَ أَنْ يُضَحِّيَ فَلَا يُقَلِّمْ أَظْفَارَهُ وَلَا يَحْلِقْ شَيْئًا مِنْ شَعْرِهِ فِي الْعَشْرِ الْأُوَلِ مِنْ ذِي الْحِجَّةِ
