This research shows a controversial syntactic question by the giant of syntax and exegesis on Sibawaihi's orientation of Robbery verse in the Glorious Qurān. We preferred to divide the study into two parts, though both have a general perspective to explain its ambiguity. The first one is listed under the title "The Predicate of the Subject in the Nominal Sentence". While the second has the heading "Reading the Accusative".The controversy of the first case has started in theorizing the rules of syntax according to the exegetist and those who consulted the surface meaning. As for the controversy of the second one (Reading the Accusative) was much more apparent to the extent that those who disagreed Sibawaihi's viewpoint were considered as audacious. The research concludes that the semantic element is closely linked with the syntactic one. Sibawaihi was not only after the syntactic view point but also the semantic one.
