I mean it's hard to find data that doesn't come from people like the Anti-defamation League (whose claims should obviously be dismissed), so you'll have to make do with examples, but there are plenty of examples:

In July 1990, the Palestinian Liberation Organization-affiliated Palestinian Red Crescent published an article in its magazine Balsam claiming that Jews concocted, "The lie concerning the gas chambers." Gradually, throughout the 1990s, Holocaust denial became commonplace in popular media in the Middle East, particularly in the Palestinian Authority.

The Grand Mufti of Jerusalem Sheikh Ekrima Sa'id Sabri appeared on the Saudi satellite channel Al-Majd on February 20, 2005, commenting on the assassination of the former Lebanese Prime Minister Rafik Hariri. "Anyone who studies The Protocols of the Elders of Zion and specifically the Talmud," he said, "will discover that one of the goals of these Protocols is to cause confusion in the world and to undermine security throughout the world."

Now it's possible that these statements by political and religious leaders don't represent the broader populace, but nothing I've seen suggests this, nor would it track with the attitude of other peoples who have suffered oppression for a long time. The opposite would also track with the long history of Palestinian terror attacks (not resistance, which is obviously valid and just, but specifically the terror attacks, which BTW aren't restricted to Hamas); the assumption seems to be that most if not all Jews are Zionists out for their blood. The problem here is that the only Jews the vast majority of Palestinians will interact with or see in the news are murderous Zionists, so the mental model of "Jew = murderous Zionist" works well enough to just be accepted as fact.

Edit: Slight rephrasing, content is the same.
