That the Prophet (ﷺ) said: "When one of you eats food, and he drops a pieces of it, then let him remove anything suspicious from it and eat it. Do not leave it for Ash-Shaitan."

He said: There is something about this from Anas.
Jami` at-Tirmidhi Book 25, Hadith 16
← Previous Hadith That Messenger of Allah (ﷺ) said: "When one of you eats, then let him lick his fingers, for indeed he does not know in which of them is the blessing."

He said: There are narrations on this topic from Jabir, Ka'b bin Malik, and Anas.

This Hadith is Hasan Gharib, we do not know of it except from this route, as a narration of Suhail. I asked Muhammad about this Hadith, so he said: "This is among the diverse narrations of 'Abdul-'Aziz, we do not know of it except from his narration."

Jami` at-Tirmidhi Book 25, Hadith 15 Next Hadith → "When the Prophet (ﷺ) ate, he would lick his three fingers, and he said: 'If one of you drops a piece (of food) then let him remove any harm (dirt) from it and eat it, and do not leave it for Ash-Shaitan.' And he would order us to finish (clean) the dish. And he said: 'Indeed you do not know in which part of your food is the blessing.'

This Hadith is Hasan Gharib Sahih.
