TABARANI 4918:
from Famī Waʾidhā Akalt Laʿiqt Aṣābiʿī Faʾinnī —
[Machine] I drink until my breath stops, then I lift the cup from my mouth. And when I eat, I lick my fingers. For I heard the Messenger of Allah ﷺ say, "When one of you eats, let him lick his fingers, for he does not know in which of his food the blessing lies."
الطبراني ٤٩١٨:
عن فمي وءذا اكلت لعقت اصابعي فءني —
أَشْرَبُ حَتَّى إِذَا انْقَطَعَ النَّفَسُ رَفَعْتُ الْإِنَاءَ عَنْ فَمِي وَإِذَا أَكَلْتُ لَعِقْتُ أَصَابِعِي فَإِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «إِذَا أَكَلَ أَحَدُكُمْ فَلْيَلْعَقْ أَصَابِعَهُ فَإِنَّهُ لَا يَدْرِي فِي أَيِّ طَعَامِهِ تَكُونُ الْبَرَكَةُ»
