(18) باب اسْتِحْبَابِ لَعْقِ الأَصَابِعِ وَالْقَصْعَةِ وَأَكْلِ اللُّقْمَةِ السَّاقِطَةِ بَعْدَ مَسْحِ مَا يُصِيبُهَا مِنْ أَذًى وَكَرَاهَةِ مَسْحِ الْيَدِ قَبْلَ لَعْقِهَا
Ibn 'Abbas reported Allah's Messenger (may peace be upon him.) as saying:
When any one of you eats food he should not wipe his hand until he has licked it himself or has given it to someone else to lick. (ES)
