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 gave forty lashes and Abu Bakr gave forty lashes' and 'Umar gave eighty and all are Sunnah.
