Exclusive 0402_sylvester_mohamed_02
A contractor who is being sued by Sylvester Stallone over a construction project gone bad is now lashing out himself … claiming in new legal docs the actor abused his dog and threatened to blow the contractor”s head off.

Mohamed Hadid just got a temporary restraining order against Sly, claiming the “Rocky” star walked up to him in court, pushed him and threatened, “I am going to kill you motherf****r.” 

Sly is about to go to trial in his legal war against Hadid, claiming the contractor royally screwed up his house to the tune of $1.4 million, calling him an “unscrupulous, unlicensed predator.”

Hadid claims in his new legal docs … while he was working on Sly”s house, he witnessed the actor fly into fits of rage … at times grabbing his dog by the neck and throwing it into its crib.  Hadid also claims Sly threatened to smash his head in with a baseball bat. 

And there”s this allegation …. Hadid says Sly once said, “Get these dirty Mexicans out of here or I will blow your head off.”

Sly”s lawyer, Marty Singer, says the actor was never notified of a hearing for a restraining order, adding Sly”s trial is about to begin and this is just a desperate attempt to smear him.  Singer says he took Hadid”s deposition last week and asked about all the conversations he had with Sly — and no threats were ever mentioned.

Singer says, “This is a desperate attempt by a man who wants to be a media star, which is why he”s a guest star on “Shahs of Sunset.””
