Are you allowed to hit the frisbee out of a players hand?

In official Ultimate Frisbee rules, players are not allowed to hit the frisbee out of an opponent's hand. Doing so is considered a foul, as it can lead to dangerous play and disrupt the spirit of the game. Players must use their body position and skill to intercept or defend against passes without physically striking the disc. Always check the specific rules of the league or tournament, as they may have variations.
