Anas bin Malik reported,

The Messenger of Allah ﷺ had the finest character of all people. I had a brother called Abu Umayr, who I believe had just been weaned. Whenever the Messenger of Allah ﷺ came and saw him, he would say, "Abu Umayr, what happened to the little nughayr bird?" He used to play with him.

Muslim 5622
