Is there a single word in English that describes when someone tries to make others hate each other or fight? So, for example, If person A and B are neighbors, so in this situation Person C tries to tell person A that person B might be taking a bit of their land. And tells person B that person A might be hooking up to their water intake. etc... It doesn't have to involve just two people. Maybe C tries to do the same between A, B, D, E, etc.
We have a similar word in Arabic, "فتنة" (fitna), which can mean various things, but this is one of its meanings.
I will give two examples on how this might work.
Person A is <the intended word> between B and C.
OR
Person A is doing a <another version of the word> between B and C.
