the Laws of the Game in football (soccer) are set by the International Football Association Board (IFAB). According to the laws, a handball offense occurs if a player deliberately handles the ball, including touching the ball with their hand or arm when the hand or arm has made their body unnaturally bigger.

If a defender kicks the ball and it unintentionally hits a teammate's hand or arm, it is generally not considered a handball offense. The key factor is whether the contact was deliberate or not. If the handball is accidental and the player had no intention of handling the ball, it is not typically penalized.
