باب اسْتِحُبَابِ لَعْقِ الْأَصَابِعِ وَالْقَصْعَةِ ، وَأَكُلِ اللُّقْمَةِ السَّاقِطَةِ بَعْدَ مَسْحِ مَا يُصِيبُهَا مِنّ أَذًي ، وَّكَراهَةِ مَسْح الْيَدِ قَبْلَ لَعْقِهَا لِاحْتِمَالِ كَوْنِ بَرَكَةِ الطَّعَامِ فَي ذٰلِكَ الْبَاقِي وَ أَنَّ السُّنَّةُ الْأَكْلُ بِثَلَاثِ أَصَابِعَ
Chapter: It is recommended to lick one's fingers and wipe the bowl, and to eat a piece of food that is dropped after removing any dirt on it. It is disliked to wipe one's hand before licking it, because of the possibility that the blessing of the food may be in that remaining part. The Sunnah is to eat with three fingers
