Narrated Abdullah ibn Abbas:

The Messenger of Allah ﷺ took a shoulder (of goat's meat) and after wiping his hand with a cloth on which he was sitting, he got up and prayed.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا أَبُو الأَحْوَصِ، حَدَّثَنَا سِمَاكٌ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ أَكَلَ رَسُولُ اللَّهِ ﷺ كَتِفًا ثُمَّ مَسَحَ يَدَهُ بِمِسْحٍ كَانَ تَحْتَهُ ثُمَّ قَامَ فَصَلَّى .
