question #1 Sahih al-Bukhari 5408, Book 70, Hadith 36 : What does this incident suggest about the necessity of performing ablution before prayer after eating?

that he saw the Prophet (ﷺ) holding a shoulder piece of mutton in his hand and cutting part of it with a
knife. Then he was called for the prayer whereupon he put down the shoulder piece and the knife with
which he was cutting it, and then stood for prayer without performing ablution again.
