جامع الترمذي#2172SahihTariq bin Shihab said:"The first to advance the Khutbah before the Salat was Marwan. A man stood to say to Marwan: 'You have contradicted the Sunnah.' So he said: 'O so-and-so! What was there it has been left.' So Abu Sa'eed said: 'As for this, he has fulfilled what is upon him. I heard the Messenger of Allah (s.a.w) saying: 'Whomever among you sees an evil, then let him stop it with his hand. Whomever is not able,then with his tongue, and whomever is not able, then with his heart. That is the weakest of faith
