Pregnancy and Parenting

Will parents be sinful for not giving their children a proper upbringing?

Q: Someone told me that if parents don’t do proper upbringing of children they will be held accountable for it, but everyone is accountable for himself, how do I reconcile between that?

Also if parents are sinful if they don’t teach about a sin to a child and he does it, someone told me that parents won’t be sinful if they don’t directly guide the child to that particular sin, but they will be held accountable for not guiding them. Is it correct?

Treating one's children unjustly

Q: I know a man in our neighbour who is married twice. He divorced his first wife and has a daughter from her who is living with him not with her mother. And from the second wife he has a daughter too. But he does clear injustice between his daughters in many ways.

On social media he always posts pictures of his daughter from his current wife and never mentions the elder daughter. I know that girl is hurt by the deeds of her own father. And instead of asking her father, people ask that girl why your father does not post pics or mention you, why does he not care about you? She is always bullied by the people. What do you say about that man and will the poor girl be rewarded in the Aakhirah due to her sabar? 

Concern for the upbringing of one's children

Q: My husband, three children and I live in a town where there are no proper mosques. I have been trying to convince him to move to a place where my children can regularly go to mosque and learn the Quraan. I have been trying for the past fifteen years but he refuses to move. I am very worried for my children as they are surrounded by non-muslim friends. My husband plans to take the children back home to visit every 2/3 years and says that they can pick up the culture from there. What does Islam say about this?
