Engagement

If she is a practicing Muslim woman and there is no legitimate reason for breaking this promise, it is not recommended to break it. But if she is not a suitable woman or not practicing or is not chaste, you must break your promise.

This differs from one person to the other. Observing the prayer, good temper and fairness are among the good characteristics.

It can be done both ways.

The Prophet salla Allahu alaihi wa sallam said to his companion: if you can see what invites you to marry a woman, go ahead. That is why scholars say that it is permissible to come out to the brother in her normal clothes she wears in her house, exposing her face, neck, hair and arms.

It is like any other marriage. He can inform those who are around him and he is not obliged to inform everyone.

The marriage contract has to have the proposal from the guardian and the acceptance of the man, the consent of the woman and the presence of two witnesses. Reciting the Fatiha is an innovation and has no significance in the marriage. These two are not married yet and they are total strangers.

  … The walimah is not an essential part of the marriage and it can be made few days after the contract.

It is best to make it in the home.

This is not permissible and neither talking to them as they are non Mahram to you. you can’t have such socialization with your fiancé until you are married. Her sister is a total stranger before and even after marriage.

It is permissible both ways.
