Replying to a person who has a lack of understanding

Q: I received this message and wanted to comment back to help him correct what needs to be corrected, but I wanted some guidance on how to respond.

"True... But Muslim social norms today mean women do not interact with men therefore they do not know whom they want to marry... In the time of the Prophet and Sahabi there was much more interaction. Indeed women would pray behind men. Therefore women knew who they were marrying... We have messed up the system. In our system (not Islamic. Just ultra conservative) women are forced to marry who their parents want them to... Those marriages are technically nil and void. Woman can walk away and say I'm technically not married. Furthermore we have created huge stigma on divorce... even though this was recorded and documented all the way back to Ismail A.S. it should be so easy for a divorcee to get re married but our messed up system rejects them unfortunately... Sad"

Claiming a share in a property

Q: My father in law was alive when he distributed his property between his both sons. At that time, one daughter was married and she said that she does not want anything from her father's property. One daughter was unmarried and my father in law was unhappy with her so he didn't give her any right in his property.

The property of my father in law was divided between both his sons only. My father in law passed away some 14 years back and now the married daughter is asking for her share in the property which she refused when my father in law was alive.

My question is, does the married daughter have the right to ask for her share in the property now from her brothers?

Unauthentic reports regarding the birth of Hazrat Nabi (sallallahu alaihi wasallam)

Q: Recently I heard a bayaan that three things happened when our beloved Nabi Muhammad (sallallahu alaihi wasallam) was born.

1. He was born without an umbilical cord.

2. He was born without any blood stains on his body which usually is the case with every new born baby.

3. He was born with khatnah.

But he didn't mention any reference of Hadith. Before passing on this information to someone else, I would like to ask you if the above mentioned things are mentioned in the mubarak hadith's.
