It was narrated from Abu Saeed Al-Khudri that the Messenger of Allah ﷺ passed by a boy who was skinning a sheep. The Messenger of Allah ﷺ said to him: "Step aside and I will show you how." The Messenger of Allah ﷺ put his hand between the skin and the flesh, and thrust his arm in until it disappeared up to the armpit, and said: "O boy, this is how you skin it." Then he went and led the people in prayer and did not perform Wudu.
