Rights of servants

Q: My parents are no more. During my mother’s lifetime, due to various reasons, I was sometimes harsh with her. I used to shout at her and speak rudely, and unfortunately I could not ask for her forgiveness while she was alive. 

However, during the final stage of her life, around two hours before her death, she became very ill and I took care of her sincerely. At that time, she gave me many duas. But throughout my life before that, I regret that I was often rude to her. 

Whenever I pray Salah, I constantly ask Allah for forgiveness for the way I behaved with my mother. Even after her death, I once saw her in a dream. In the dream, I was saying to her, “Please forgive me, Mom. If you do not forgive me, Allah may also not forgive me.” She did not say anything and was only looking at me. 

Please guide me on how I can seek forgiveness properly and how a person can know if Allah has forgiven them for such a sin.

Q: We are 4 children (2 daughters and 2 sons). My father passed away a few months ago. Who is responsible for taking care of and for the financial needs of my mother?

Q: What are the responsibilities of a daughter, who is an only child, towards her mother, who is a single parent? 

Do any of these responsibilities change upon the daughter getting married? 

What are the rights that her mother has over her?

Q: My son left the fold of Islam many years ago. We broke ties with him. Can I contact him now? Would I be sinful if I contact him since he is a murtad?

Q: Does my father have to take responsibility of his sister whose husband died but she has a son whose age is 20+? Will my father be a sinner if he doesn't take responsibility of his sister? The son is unemployed.

Q: I have a question regarding milk parents. 

I was conceived by my biological parents with the intention of being adopted by my aunty (fathers sister) as she hadn’t had any children with her husband for 11 years. 

When I was born, I was adopted and grew up in another city with my (new) milk parents. From small I was told about my adoption so it wasn’t something shocking to me. 

I grew up knowing my siblings and visiting my biological parents often, but my milk parents were like my real/main parents and my biological were like my aunty and uncle. 

Now that I’m older and married and my siblings are also older and married and I’m staying in the town I grew up with my biological parents. I hadn’t been there as much and made the khidmat owed to my biological parents. 

My biological parents said multiple times that I should treat my milk parents as my real ones and that they (the biological ones) hold no haq over me. I asked my shaikh what to do and he says that shariah is above everything and that their words or emotions don’t govern what the actual rights to them are. 

So my question is who holds more right over me, the milk parents who raised me or the biological parents who bore me? 

When it comes to khidmat or instruction, who holds more weight? 

And lastly, if they excuse me from khidmat what does it mean?

Q: I want to know if it is permissible for family to stay away from other family members who have sexually molested their child.
