حَدَّثَنَا مَحْمُودٌ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنِ الْمِسْوَرِ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ ﷺ نَحَرَ قَبْلَ أَنْ يَحْلِقَ، وَأَمَرَ أَصْحَابَهُ بِذَلِكَ.

That Abdullah and Salim said to 'Abdullah bin 'Umar, "(You should not go for Hajj this year)."

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الرَّحِيمِ، أَخْبَرَنَا أَبُو بَدْرٍ، شُجَاعُ بْنُ الْوَلِيدِ عَنْ عُمَرَ بْنِ مُحَمَّدٍ الْعُمَرِيِّ، قَالَ وَحَدَّثَ نَافِعٌ، أَنَّ عَبْدَ اللَّهِ، وَسَالِمًا، كَلَّمَا عَبْدَ اللَّهِ بْنَ عُمَرَ ـ رضى الله عنهما ـ فَقَالَ خَرَجْنَا مَعَ النَّبِيِّ ﷺ مُعْتَمِرِينَ، فَحَالَ كُفَّارُ قُرَيْشٍ دُونَ الْبَيْتِ، فَنَحَرَ رَسُولُ اللَّهِ ﷺ بُدْنَهُ، وَحَلَقَ رَأْسَهُ.
