Well, imagine Neville Longbottom coming across the Jafar's staff. He's always been a bit clumsy but also brave. He might initially be intimidated by the staff but then decides to stand up to it.

They would start to experiment with different spells and potions to see if they could nullify the staff's power. They might also try to communicate with it, thinking that it could be like a magical creature with its own intelligence, and through this communication, they could either gain control over it or find a way to get rid of it.
One possible plot could be that the Jafar's staff somehow finds its way into the wizarding world of Harry Potter. Maybe a dark wizard discovers it and tries to use its power in Hogwarts. Harry and his friends then have to figure out how to stop the dark magic of the staff from taking over the school.
