Mishkat al-Masabih #305

Anas b. Malik said: Ubayy, Abu Talha and I sat and ate some meat and bread, after which I called for water to perform ablution. They asked, “Why are you performing ablution?” and I replied that it was because of this food which we had eaten. They said, “Do you perform ablution after eating things which are good? He who was better than you did not perform ablution on that account.” Ahmad transmitted it.
