[Heacechig]

I had once heard in a bayan a hadith something to the effect of, that Hadrat Aisha narrated that even if 100 people had eaten together, she would be able to spot the Prophet's plate out of all of their plates because his plate would be the cleanest (due to him having cleaned it so well with his fingers etc).

I am looking for that specific hadith, and other similar ahadith, which show not only that he said to wipe your plate clean, but also how well he used to wipe his plate clean.

for your help.
