Is it forbidden for a wife to remain in her husband's home after he has divorced her – despite his threats to kill her – and what are the rulings on an irrevocable divorce, and is she entitled to custody of her children?

The husband is religiously commanded to treat his wife with kindness, and it is enjoined, "Treat women kindly." His viewing of pornographic films is a reprehensible act that necessitates admonishment, and God may punish him by depriving him of lawful pleasure.

If the divorce is revocable, he has no right to expel her from the home, and she is not permitted to leave except for a legitimate excuse, such as fear of harm. If the waiting period (iddah) expires, she becomes irrevocably divorced, and she is not permitted to reside with him unless the part she occupies is independent.

Custody of the children is the mother's right unless she remarries. The husband is obliged to provide housing for the custodian if she does not have a residence, as this is part of the child's maintenance.

It is advisable to consult the Sharia court to resolve these matters, as they are often subjects of dispute and disagreement among jurists.
