Abu Hurairah:
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.
[Abu 'Eisa said:] 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."
