In reply to the above letter, Muawiyah used insolent words, and maintained the accusation against Ali of murdering Othman. Ali replied to this letter in the following terms: "I have received your letter which is a tissue of lies, and which shows your evil nature. Your letter is a letter of a person, who has neither the light to lighten the dark way, nor any guide to lead him. It is the letter of a person who is obsessed with his ulterior motive, and is deliberately treading the way of perdition. Your letter is meaningless and baseless. Under the law there is only one "baiy'at" which has been held. It has attained finality and is not susceptible of any review or revision. He who objects to the "baiy'at" in fact denounces Islam."
