Sunan Abi Dawud 1766
Narrated Arfah ibn al-Harith al-Kandi:
I was present with the Messenger of Allah (ﷺ) at the Farewell Pilgrimage. When the sacrificial camels were brought to him, he said: Call AbulHasan (Ali) to me. Ali was then called for and he (the Prophet) said to him: Catch hold of the lower end of the lance, and the Messenger of Allah (ﷺ) himself caught hold of the upper end. He then pierced the camels with it. When he finished slaughtering, he rode on his mule and mounted Ali behind him.
حَدَّثَنَا مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْمُبَارَكِ، عَنْ حَرْمَلَةَ بْنِ عِمْرَانَ، عَنْ عَبْدِ اللَّهِ بْنِ الْحَارِثِ الأَزْدِيِّ، قَالَ سَمِعْتُ غَرَفَةَ بْنَ الْحَارِثِ الْكِنْدِيَّ، قَالَ شَهِدْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فِي حَجَّةِ الْوَدَاعِ وَأُتِيَ بِالْبُدْنِ فَقَالَ ‏"‏ ادْعُوا لِي أَبَا حَسَنٍ ‏"‏ ‏.‏ فَدُعِيَ لَهُ عَلِيٌّ - رضى الله عنه - فَقَالَ لَهُ ‏"‏ خُذْ بِأَسْفَلِ الْحَرْبَةِ ‏"‏ ‏.‏ وَأَخَذَ رَسُولُ اللَّهِ صلى الله عليه وسلم بِأَعْلاَهَا ثُمَّ طَعَنَ بِهَا فِي الْبُدْنِ فَلَمَّا فَرَغَ رَكِبَ بَغْلَتَهُ وَأَرْدَفَ عَلِيًّا رضى الله عنه ‏.‏
