Sahih Muslim | Book 17 | Hadith Number 4228

Narrated by Anas b. Malik
Anas b. Malik reported that Allah's Apostle (may peace be upon him) gave a beating with palm branches and shoes, and that Abu Bakr gave forty lashes. When Umar (became the Commander of the Faithful) and the people went near to pastures and towns, he said (to the Companions of the Holy Prophet). What is your opinion about lashing for drinking? Thereupon Abd al-Rahman b. Auf said: My opinion is that you fix it as the mildest punishment. Then 'Umar inflicted eighty stripes.
