Purdah

Q: A woman doesn't observe pardah (covering her face). 

She works in a home. There is a man and a woman. The man observes pardah from her. When she comes to work, she comes walking and without pardah. The employees have tried to encourage her to wear pardah but to no avail. 

Now she is offered a job at another place. There it is not clear who she will come into contact with. 

My question is, if a person suggests for her to take the job, is the person sinful because she will come into contact with men. She isn't observing pardah, she is also leaving the house to come to work, so on the way she is going to come across men.

Q: If a female who was born out of wedlock and raised by her maternal grandparents as their own, who is her Mahram? 

Does her uncles, her mother's brothers become her Mahram? Will her brother, they share the same mother but not father become her Mahram? 

And are her male cousins, sons of her mother's sister's and brother's become her Mahram?

Q: I am working as teacher in a Higher Secondary School, where students of age group 14-18 are enrolled. 

Is it permissible in Islam for a male teacher to place his hand on the head of a female student as a gesture of affection and encouragement.

Q: I observed Hijab (with face cover) but my wedding is near and when my marriage proposal came, my mother in law requested me not to cover my face in front of my brother-in-law after marriage. I feared that time and I agreed to her but now I'm confused if Islam allows it or not. Please guide me regarding that.

Q: 

Can I keep a non mahram as a Facebook friend? If I don't talk with them unnecessarily & don't post any photo of mine? Will it be considered as zina for me? Can I give likes to the posts of non mahrams or will it be considered as zina? 

Can I give salam to my non mahram relatives? Will it be considered as zina?

Q: Where I'm working, I know the people quite well. I've been working here for about 3 years or so now. 

They give me duties to do, example, to take their mother or wife or sister to go shopping or to transport them from one place to another. 

I personally don't like doing that because they are non mahram. My wife gets angry with me when I do those things and she doesn't speak to me. 

If I do tell my boss that I can't do those duties, I know personally they will fire me or treat me differently although they are Muslims. What should I do?

Q: I just applied for a part-time job and they require that I remove my pardah (niqaab). I usually do not wear it in my home town due to my home situation as a revert and my family is against it and out of respect for them I do not wear it. However I made the intention to wear it full time even though my family would still disagree. 

My question is: What is the ruling on this and would it be advisable to wear it even though it may cause arguing and tension at home, and should I ever take off my niqaab (in future) for the sake of a job?

Q: I have a sister who is the daughter of my fathers brother and mother's sister, my question is that is she a mahram for me?

Q: A girls father in law wants to shake her hand when they go to visit. It's a habit of his to shake his nieces hands and hug them. 

On Eid he shook her hand and kissed it. The mother in law said he's doing like how Dada used to do for the children. 

Is this allowed ?

Q: Is it permissible for the son in law to hug his mother in law if she is not old?
