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 ‘Abbas said that God's messenger ate a shoulder, and after wiping his hand with a cloth on which he was sitting, he got up and prayed. Abu Dawud and Ibn Majah transmitted it.
