باب نَحْرِ الْبُدْنِ قَائِمَةً
وَقَالَ ابْنُ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا سُنَّةَ مُحَمَّدٍ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ.
وَقَالَ ابْنُ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا: {صَوَافَّ} قِيَامًا.

Narrated Anas:

The Prophet (ﷺ) offered four rak`at of Zuhr prayer at Medina; and two rak`at of `Asr prayer at Dhil- Hulaifa and spent the night there and when (the day) dawned, he mounted his Mount and started saying, "None has the right to be worshipped but Allah, and Glorified be Allah." When he reached Al- Baida' he recited Talbiya for both Hajj and `Umra. And when he arrived at Mecca, he ordered them (his companions) to finish their Ihram. The Prophet (ﷺ) slaughtered seven Budn (camel) with his own hands while the camels were standing He also sacrificed two horned rams (black and white in color) at Medina.

حَدَّثَنَا سَهْلُ بْنُ بَكَّارٍ، حَدَّثَنَا وُهَيْبٌ، عَنْ أَيُّوبَ، عَنْ أَبِي قِلاَبَةَ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ صَلَّى النَّبِيُّ صلى الله عليه وسلم الظُّهْرَ بِالْمَدِينَةِ أَرْبَعًا، وَالْعَصْرَ بِذِي الْحُلَيْفَةِ رَكْعَتَيْنِ، فَبَاتَ بِهَا، فَلَمَّا أَصْبَحَ رَكِبَ رَاحِلَتَهُ، فَجَعَلَ يُهَلِّلُ وَيُسَبِّحُ، فَلَمَّا عَلاَ عَلَى الْبَيْدَاءِ لَبَّى بِهِمَا جَمِيعًا، فَلَمَّا دَخَلَ مَكَّةَ أَمَرَهُمْ أَنْ يَحِلُّوا‏.‏ وَنَحَرَ النَّبِيُّ صلى الله عليه وسلم بِيَدِهِ سَبْعَ بُدْنٍ قِيَامًا، وَضَحَّى بِالْمَدِينَةِ كَبْشَيْنِ أَمْلَحَيْنِ أَقْرَنَيْنِ‏.‏
