حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ الْخَلَّالُ قَالَ: حَدَّثَنَا عَفَّانُ قَالَ: حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ قَالَ: «كَانَ النَّبِيُّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ إِذَا أَكَلَ طَعَامًا لَعِقَ أَصَابِعَهُ الثَّلَاثَ»
It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that he said: When the Noble Prophet, peace and blessings be upon him, finished eating food, he would lick his three fingers.
