It was narrated that Ibn 'Abbas said:
"The Messenger of Allah ate a shoulder, then he wiped his hands on a Mish that was underneath him, then he got up for prayer, and performed the prayer.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ أَكَلَ النَّبِيُّ ﷺ كَتِفًا ثُمَّ مَسَحَ يَدَيْهِ بِمِسْحٍ كَانَ تَحْتَهُ ثُمَّ قَامَ إِلَى الصَّلاَةِ فَصَلَّى .
