How do you approach prenup without looking greedy as a woman?

This is not greed.

This is what Islam says.

The woman's money is the woman's money.

The man has no right to it. No right to say how she spends it.

She doesn't have to spend that money on her own clothing, her own food, or her own shelter.

That is the husband's responsibility islamically traditionally speaking.

So, I think this is a matter of the man needs to be educated as what is his role and what is his wife's role?

Maybe both of you sign up for the nikah masterclass. Maybe you share some videos. I think education is really going to be the highest thing.

That might be one approach to bringing up a prenup with your husband.
