و قَالَ سُفْيَانُ عَنْ عَمْرٍو عَنْ عَطَاءٍ عَنِ ابْنِ عَبَّاسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِذَا أَكَلَ أَحَدُكُمْ فَلَا يَمْسَحْ يَدَهُ حَتَّى يَلْعَقَهَا أَوْ يُلْعِقَهَا
مسند امام احمد بن حنبل · Hadith 1924
It was narrated from Ibn 'Abbas that the Prophet (PBUH) said; "When one of you eats, let him not wipe his hand until he has licked it or it is licked for him."
