Riyad as-Salihin 164

Translation

Jabir (May Allah be pleased with him) reported: Messenger of Allah (PBUH) commanded the licking of fingers (after eating) and the cleaning of the dish, saying: "You do not know in what portion the Blessing (of Allah) lies". [Muslim]. In another narration, Jabir said: Messenger of Allah (PBUH) said, "When a morsel of any of you falls down, you should pick it up and remove any dirt or dust on it and then eat it; and don't leave it for Satan; and do not wipe your hand with the towel until you have licked your fingers, for you do not know in what portion of the food the Barakah* (of Allah) lies". * Barakah is the abundance of goodness and its continuity.

• Riyadhus Shalihin 750- وعنه أن رسول الله صلى الله عليه وسلم قال: "إذا وقعت لقمة أحدكم، فليأخذها فليمط ما كان بها من أذى وليأكلها، ولا يدعها للشيطان، ولا يمسح يده بالمنديل حتى يلعق أصابعه؛ فإنه لا يدرى في أي طعامه البركة".((رواه مسلم))
• Shahih Muslim 2033bإِذَا وَقَعَتْ لُقْمَةُ أَحَدِكُمْ فَلْيَأْخُذْهَا فَلْيُمِطْ مَا كَانَ بِهَا مِنْ أَذًى وَلْيَأْكُلْهَا وَلاَ يَدَعْهَا لِلشَّيْطَانِ وَلاَ يَمْسَحْ يَدَهُ بِالْمِنْدِيلِ حَتَّى يَلْعَقَ أَصَابِعَهُ فَإِنَّهُ لاَ يَدْرِي فِي أَىِّ طَعَامِه
