The agents of Mu'awiyah endeavoured to make matters doubtful for him and said: "There is no question of 'Ammar being in Siffin. The Iraqis do not mind coining such lies". Zul Kala' was not however, convinced. He turned to 'Amr As and said: "Has the Prophet said such and such words about 'Ammar? Ibn As said: "Yes, he has said so, but 'Ammar is definitely not in Ali's army". He said: "I shall investigate the matter personally". Then he deputed some persons to verify the position.
