Is there a sin upon one who wished for a person to taste the same pain they had experienced, and then that person died two days later?

If a woman wrongs you and you supplicate against her to the extent of her wrongdoing, then there is no sin. However, if she did not wrong you, or you supplicated against her beyond the extent of her wrongdoing, then you have sinned, based on the Almighty's saying: ﴿So whoever transgresses against you, transgress against him to the same extent that he transgressed against you﴾. As for envy, it is a sin of the heart.
