Re: The Red Pill/Manosphere
I’m just going to copy and paste some stuff here.
“if divorce did take place, and both parties demand their rights, then the right of custody will be in the following way. In should be remembered here that there is nothing wrong in making a mutual arrangement, as long as there is no objection from those who have a right to custody”
And then comes your part. Yes its true what you stated however that only comes about if there is no mutual agreement over the children. And the fairness of a mother remarrying comes in to protect the children of her first husband. Her first husband has a right over his children, he is their father not a stepfather. And any female children would have to do hijab before their stepfather.
It may not seem fair to you but it wasnt made up without reason or thought. Nor was it made to be unfair to the mother.
"Irrespective of who (mother/father) has the right of custody, the other party has visitation rights according to mutual understanding and consent. Generally, the party having the rights of custody use the child as a weapon to punish the other party by depriving them of visitation rights. This is totally against the concept of Islam and a severe, brutal and grave sin indeed, and also very harmful to the child. Unfortunately, many so called “religious” people are also involved in this heinous act.
At all times, the father of the child is responsible for maintaining the child; in the case of a female, until she marries; while in the case of a healthy male, until he reaches maturity. In the case of a disabled child (male or female) the father is permanently responsible.
When the mother has the rights of custody but does not have a shelter to stay in with the child, the father must provide shelter for both."
