حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ الْخَلالُ، قَالَ: حَدَّثَنَا عَفَّانُ، قَالَ: حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، قَالَ: كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا أَكَلَ طَعَامًا لَعِقَ أَصَابِعَهُ الثَّلاثَ.
Anas said:
“When the Prophet (Allah bless him and give him peace) ate a meal, he used to lick his three fingers [the thumb, the index finger and the middle finger].”
