Hadith 1977
Umm Salama reported Allah's Messenger (may peace be upon him) having said this: When any one of you intending to sacrifice the animal enters in the month (of Dhu'l-Hijja) he should not get his hair or nails touched (cut). It was said to Sufyan that some of the (scholars) did not deem this hadith to be Maffu'. He said: But I deem it as Marfu' (i. e. chain of narration traceable right up to the Holy Prophet).
حَدَّثَنَا ابْنُ أَبِي عُمَرَ الْمَكِّيُّ، حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ، بْنِ عَوْفٍ سَمِعَ سَعِيدَ بْنَ الْمُسَيَّبِ، يُحَدِّثُ عَنْ أُمِّ سَلَمَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " إِذَا دَخَلَتِ الْعَشْرُ وَأَرَادَ أَحَدُكُمْ أَنْ يُضَحِّيَ فَلاَ يَمَسَّ مِنْ شَعَرِهِ وَبَشَرِهِ شَيْئًا " . قِيلَ لِسُفْيَانَ فَإِنَّ بَعْضَهُمْ لاَ يَرْفَعُهُ قَالَ لَكِنِّي أَرْفَعُهُ .
