Arabic hadith text
وَعَن ابْن عَبَّاس قَالَ: أَكَلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَتِفًا ثُمَّ مَسَحَ يَده بِمِسْحٍ كَانَ تَحْتَهُ ثُمَّ قَامَ فَصَلَّى. رَوَاهُ أَبُو دَاوُد وَابْن مَاجَه وَأحمد
Translation
Ibn ʿAbbās said that the Messenger of God ate a shoulder, wiped his hand with a cloth that was beneath him, then stood and prayed. Abū Dāwūd, Ibn Mājah, and Aḥmad transmitted it.
Translation notes
The accompanying grading labels this report ḥasan (good). The Arabic does not specify the animal whose shoulder he ate.
