Abu Dawud Book 33, Hadith Number 4472.

Narated By AbdurRahman ibn Azhar : I can still picture myself looking at the Apostle of Allah (PBUH) who was among the camps of the Companions seeking the camp of Khalid ibn al-Walid, when a man who had drunk wine was brought before him. He asked the people: Beat him. Some struck him with sandals, some with sticks and some with fresh branches of the palm-tree (mitakhah). Ibn Wahb said: This (mitakhah) means green palm fronds. Then the apostle of Allah (PBUH) took some dust from the ground and threw it on his face.
