Sahih al-Bukhari 5511

Narrated Asma':

We slaughtered a horse (by Dhabh) during the lifetime of Allah's Messenger (ﷺ) while we were at Medina, and we ate it.

حَدَّثَنَا إِسْحَاقُ، سَمِعَ عَبْدَةَ، عَنْ هِشَامٍ، عَنْ فَاطِمَةَ، عَنْ أَسْمَاءَ، قَالَتْ ذَبَحْنَا عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَرَسًا وَنَحْنُ بِالْمَدِينَةِ فَأَكَلْنَاهُ‏.‏
