What is the Islamic legal ruling on holding wedding parties with designated tables for families, accompanied by Islamic songs and speeches, without music or dancing? And what is the ruling on friends or brothers and their wives meeting together, with the presence of hijab, for conversation, and then separating when it is time to eat?

There is no harm in families gathering if it is possible for some of them not to see others, or hear their conversations, or see what is not permissible to see. The forbidden mixing is that which is not regulated by Sharia (definition) controls.

Scholars differed on what part of a non-mahram (definition) woman is permissible to look at. The most correct opinion is that the face and hands are 'awrah, so it is not permissible to look at them. As for the hair and the rest of the body, it is not permissible to look at them.

There is no harm in Islamic songs, especially at weddings.

It is not permissible for friends or brothers to gather with their wives due to the Sharia prohibitions that arise from it and the lack of security from temptation, even if the women are in their hijabs.

It is not permissible for friends or brothers to gather with their wives to talk and laugh together, unless they are brought together by necessity (like a car or an airplane), while observing the Sharia controls such as complete covering and not softening the voice or speaking flirtatiously.
