The Book Pertaining to Punishments Prescribed by Islam (Kitab Al-Hudud)
Muslim :: Book 17 : Hadith 4228
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.
