Narrated Asma':
حَدَّثَنَا إِسْحَاقُ ، سَمِعَ عَبْدَةَ ، عَنْ هِشَامٍ ، عَنْ فَاطِمَةَ ، عَنْ أَسْمَاءَ ، قَالَتْ ذَبَحْنَا عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَرَسًا وَنَحْنُ بِالْمَدِينَةِ فَأَكَلْنَاهُ.
We slaughtered a horse (by Dhabh) during the lifetime of Allah's Messenger (ﷺ) while we were at Medina, and we ate it.
