Don't cause any arguments repeating inflammatory words Don't cause any disputes repeating inflammatory words.

The parts of your sentences that are awkward are "any" and "saying." To make any order apply generally you just need to use "a" or "an." And the verb "saying" isn't quite right, though if you change it to "by saying" it sounds better and would be more understandable ("by" expresses agency, and helps the participle explain your use of "cause"). A better verb that expresses agency and is more common in speech is "using." So, for example: "Don't cause an argument by using inflammatory words." A more typical and casual way of expressing this is: "Don't start an argument by using inflammatory language."

“Don’t use inflammatory language” is how I would say it. You could also say “don’t provoke arguments by using inflammatory language” if you need to include the first half of the sentence.
