Purdah

Q: If the wife passes away, can her mother live in the same house with the son in law as she has to take care of the children?

Q: Can you please advise me on the following matter: 

A girl was married and is now divorced from her husband. There was a child (female) from that marriage. The girl is now going to perform Nikah with someone else. 

What is the position/relationship of the child (who is now reaching puberty) to her stepfather? Is the stepfather her mahram or non-mahram?

Q:  I went for a day out with my mum and sister and thought it would be only women but when we went for food, my mums boyfriend came. Have I sinned by meeting with a man I didn't know he was gonna come? I thought it would be just women. My family are non Muslim and I didn't talk to my mums partner except to say hello. 

What's the ruling when the following happens?

Q: I recently heard someone say that it is permissible for the sister-in-law to not make parda from her brother-in-law when: 

1. There is no scope of fitna. 

2. When it becomes difficult for her to leave her own room for basic needs. 

My friend has recently married into a family of 6. They live in a small flat. Her brother-in- law is 6 years younger than her and she claims he is an actual replica of her brother in her maternal home. There isn't a chance that they can ever be alone. It becomes difficult for her to constantly be in her cloak, burkha and pardah the entire day almost as if she is at a guests home and not in a home that she has a right to stay in. What is the ruling regarding this?

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?
