Jabir told that he heard the Prophet say, “The devil is present with one of you in everything he does, even being present when he is at food; so if any of you drops a mouthful he should wipe away anything injurious on it and eat it and not leave it for the devil; and when he finishes he should lick his fingers, for he does not know in what part of the food the blessing lies.”
Qatada quoted Anas as saying that the Prophet never ate at a low table or from a small bowl* and that thin bread was not baked for him. Qatada was asked what they ate off and replied that it was off leather cloths.
*This would have indicated pride throngh keeping himself apart, or niggardliness.
