وحَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ ، حَدَّثَنَا أَبِي ، حَدَّثَنَا مُحَمَّدُ بْنُ عَمْرٍو اللَّيْثِيُّ ، عَنْ عُمَرَ بْنِ مُسْلِمِ بْنِ عَمَّارِ بْنِ أُكَيْمَةَ اللَّيْثِيِّ ، قَالَ : سَمِعْتُ سَعِيدَ بْنَ الْمُسَيِّبِ ، يَقُولُ : سَمِعْتُ أُمَّ سَلَمَةَ زَوْجَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، تَقُولُ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " مَنْ كَانَ لَهُ ذِبْحٌ يَذْبَحُهُ ، فَإِذَا أُهِلَّ هِلَالُ ذِي الْحِجَّةِ ، فَلَا يَأْخُذَنَّ مِنْ شَعْرِهِ وَلَا مِنْ أَظْفَارِهِ شَيْئًا حَتَّى يُضَحِّيَ " .
Umm Salamah, the wife of Allah's Apostle (ﷺ) , reported Allah's Messenger (ﷺ) to have said: He who has a sacrificial animal with him whom (he intends) to offer as sacrifice, and he enters the month of Dhu'I-Hijja, he should not get his hair cut or nails trimmed until he has sacrificed the animal.
