The Messenger of Allah ﷺ said, "When the morsel of one of you falls, let him pick it up, remove whatever harm has come upon it, and eat it. Let him not leave it for the devil. And let him not wipe his hand with a napkin until he has licked his fingers, for he does not know in which part of his food the blessing lies."
حدثنا محمد بن عبد الله بن نمير حدثنا أبي حدثنا سفيان عن أبي الزبير
قال رسول الله ﷺ إذا وقعت لقمة أحدكم فليأخذها فليمط ما كان بها من أذى وليأكلها ولا يدعها للشيطان ولا يمسح يده بالمنديل حتى يلعق أصابعه فإنه لا يدري في أي طعامه البركة
