“When Walid bin ʿUqbah was brought to ʿUthman, 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.'”
