مسند أحمد

It was narrated that Huzain said: Testimony was given against or Husain al-Waleed bin `Uqbah before ‘Uthman, that he drank alcohol. `Ali spoke to ‘Uthman about him and he said: Here is your cousin, flog him. He said: Get up O Hasan (and flog him). He said: What do you have to do with this man? Let someone other than you do that. He said: Rather you felt incapable and weak. Get up, O `Abdullah bin Jafar, and flog him. ‘Ali (رضي الله عنه) started counting, and when he reached forty he said. That`s enough-or:Stop-The Messenger of Allah (ﷺ) gave forty lashes, and Abu Bakr gave forty lashes, and `Umar completed it, making it eighty. And all are Sunnah.
