Hudain bin Mundhir said:“When Walid bin `Uqbah was brought to `Uthman, they had testified against him. He said to 'Ali: 'You are close to your uncle's son, so carry out the legal punishment on him.' So 'Ali whipped him. He said: 'The Messenger of Allah (ﷺ) gave forty lashes, and Abu Bakr gave forty lashes, and 'Umar gave eighty all are Sunnah.'”
