Just curious, to what degree is it actually permissible for parents to beat their kids in Islam. And if you could elaborate on when it is too much to where it becomes abuse instead of disciplining. Because I feel that alot of muslims have had it as norm to beat kids alot of times to the point where they get wounded for discipline but without any restrictions.

We are not allowed to beat our Kids under any circumstance. Let alone causing the children some injuries and wounds. Beating them will tend to make them stubborn if we don’t take care. The best way to discipline your children is to deny them certain things they like the most if they fail to live up to certain expectation. This could be denying them access to their game, phone for sometime etc
