In the name of Allah. No, let's see. I want it to be truly pre-Islamic, it might seem pre-Islamic to you but not actually be so. No, apparently its ruling is the same.
For example, we see among the customs of women that when a woman's husband dies and she is in her waiting period.
It is assumed, they think she can only wear a certain type of clothing.
They also think she cannot go out to the courtyard, they think she cannot go up to the roof.
They think she cannot look at the moon, and they claim the moon is a man. Many things like this. They also think that a woman in mourning cannot speak to anyone.
Nor can she speak to someone who asks permission at the door, all of this has no basis.
So if this is what you mean, then this is. If you mean other things, then remember them so.
