Purdah

Attending an engagement

Q: I am invited to my 1st cousins engagement. I am the only female in niqaab and I am the only person in my family who is in a Darul Uloom. I don't know if I shouldn't go because I don't want to break the law of Allah Ta'ala or must I go to keep family ties. If I don't go then my family will get really upset with me but doesn't the command of Allah Ta'ala come first?

Free mixing with non-mahrams

Q: I am a girl and two of my girl cousins recently got married and their husbands mix freely with them in playing some games such as cards or monopoly for example. They always force me to play with them and I try not to play with them anymore.

I heard that free mixing is haraam and I tried to tell them but they mocked me and said that we are just playing cards and we are not sitting near each other, there's a distance.

I wanted to ask what should I do? Am I sinful for playing with them because their husband's aren't my mahram although we keep distance? How can I convince them if it is haraam?

Having meals with non-mahrams

Q: Is it permissible for me to sit and eat with my girl cousins while her father, mother, brother and my mother are also seated there.

Also, can I say جَزَاكَ اللَّهُ خَيْرًا and speak about general things like Madrasah with her mother, who is my mother's brother's wife while they are wearing abaya and scarf but part of their hair or neck is exposed?
