Narrated Asma':

We slaughtered a horse (by Dhabh) during the lifetime of Allah's Apostle 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 ﷺ فَرَسًا وَنَحْنُ بِالْمَدِينَةِ فَأَكَلْنَاهُ.
