Basketball-who gets the point?

If the ball travels through your opponent's basket, your opponent gets the points.

Rule 5, Section I, part D of the 2014-15 NBA Rule Book

d. A field goal accidentally scored in an opponent’s basket shall be added to the opponent’s score, credited to the opposing player nearest the player whose actions caused the ball to enter the basket.

FIBA and NBA are essentially the same on the point of accidentally scoring in your own basket.

The FIBA Rules state:

16.2.2. If a player accidentally scores a field goal in his team’s basket, the goal counts 2 points and shall be recorded as having been scored by the captain of the opposing team on the playing court

In other words, if you deflect a ball during a shot, rebound or pass and the ball goes in your own basket, the field goal counts as 2 points for your opponents.

Even forgetting which basket is your own, and scoring the wrong basket still counts 2 points for the opponents.

If you accidentally get the ball in the wrong basket it counts however if it was done on purpose such as a field goal attempt it does not.

NBA rule 5 section I part D states:

A field goal accidentally scored in an opponent’s basket shall be added to the opponent’s score, credited to the opposing player nearest the player whose actions caused the ball to enter the basket.

.....However.....

NBA rule 5 section I part E: It is a violation for a player to attempt a field goal at an opponent’s basket. The opposing team will be awarded the ball at the free throw line extended.

These are essentially the same in FIBA rules:

16.2.2. If a player accidentally scores a field goal in his team’s basket, the goal counts 2 points and shall be recorded as having been scored by the captain of the opposing team on the playing court. 16.2.3. If a player deliberately scores a field goal in his team’s basket, it is a violation and the goal does not count.
