Hadith 43:61
It was narrated that Asma said:
"We slaughtered ( naharna ) a horse during the time of the Messenger of Allah while we were in Al-Madinah, and we ate it." (Sahih )
أَخْبَرَنِي مُحَمَّدُ بْنُ آدَمَ، قَالَ حَدَّثَنَا عَبْدَةُ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ فَاطِمَةَ، عَنْ أَسْمَاءَ، قَالَتْ ذَبَحْنَا عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَرَسًا وَنَحْنُ بِالْمَدِينَةِ فَأَكَلْنَاهُ
