Well there you go! Oh my, you never said she thinks he acted against Islam! That explains a lot what you are wondering about. There is no hypocrisy if she really believes and doesn't know better.Al-Zaara, you are very fiery. I want an answer to this based on what islam dictates. Not on your feelings and imaginings about my sisters relationship with her father. You are thinking too deeply about this. She is not jealous of the wife - she has never met her! She will never meet her. None of us will ever meet her. It is irrelevant. She believes my father acted against the teachings of Islam, yet is she not also acting against the teachings of Islam. Is there not some element of hypocricy here? I am not in competition to be the better Muslim. I am not a practicing Muslim. This is why I wanted to speak to others. Anyway, thank you for your thoughts.
Jamila G, you said you wanted to know why she behaves like this and you never mentioned she thinks she is Islamically right about his actions! I thought you wondered why she couldn't accept the marriage (without religious interfering), which my points were based on.
