Re: What's your Opinion : Question by a Non-Muslim man about his recently converted w
As mentioned by others already, her marriage to him is no longer valid if he does not accept Islam, so the headscarf should be the least of his worries.
How does the wife converting to islam make the marriage invalid? I don't think so for two reasons:
1) By laws of the land, once a marriage is registered, only a formal divorce or annulment is the only way to cancel it. That has not happened in this case.
2) Even by muslim law (now, I am not an authority on this of course) my understanding is that the husband has maximum authority over wife - so if the husband has not converted then the assertion that the wife's conversion is invalid is more potent and valid than the claim that the marriage is invalid.
