Ask O Muhammad those who doubt your mission: "What documentary evidence has more weight to support the truth of my mission than the attestation by Allah Himself!" "He is the witness of my actions and of your actions". "This Quran has been inspired to me to guide you into all truth and to warn you and warn all those whom it shall reach against counting Allah as being plural". "Do you people really bear witness to the plurality of Allah!" "I Just will not accord with this". Say to them: "Indeed He is only One Ilah, and I am absolutely innocent of your ills, and above all of your notion of incorporating with Him other deities".
