(Say) to the disbelievers of Mecca, O Muhammad: (I exhort you unto one thing only) with “there is no deity save Allah”: (that ye awake, for Allah's sake, by twos and singly, and then reflect) upon whether Muhammad (pbuh) is a magician, fortune teller, a liar or madman: (There is no madness in your comrade) in your Prophet. (He) Muhammad (pbuh) (is naught else than a warner) a warning Messenger (unto you in face of a terrific doom) on the Day of Judgement if you reject faith.
