In the picture: A person decided to take their "fair" share from their own personal perspective, and in the process, ruined the share of others. This person will swear an oath to tell you that they only took their right, and they would truly be speaking the truth, but they are among those who spread mischief (Fasaad).
You have every right to take your due right,
But you do not have the right to take it in a manner that seems fair only to you while harming the rights of others.
This is exactly what constitutes an abuse of exercising one's right.
