Prayer: Can someone be considered ‘ādil if they’ve also wronged me?

English:

Question #558:

A person considers another one as just and pious and at the same time considers him as an oppressor because on certain occasion he has oppressed him. So can this person consider the other as ‘ādil in the common sense of the word?

Answer #558:

Until it is not clear that the person, whom he has considered an oppressor, has done that action knowingly, by choice and without any religious excuse, it is not permissible to label him unjust.
