Is a daughter obligated to fulfill all requests of her father who habitually shouts and raises his voice, and believes that his son's wife puts magic in his food?

What you mentioned did not include a specific question. If your father treats you badly, this is an affliction whose cure is patience. No matter how much he wrongs you, he remains a father whose piety and good treatment are obligatory. Al-Bukhari dedicated a chapter in "Al-Adab Al-Mufrad" titled "Being Dutiful to One's Parents Even if They Wrong," and he mentioned a narration from Ibn Abbas, may Allah be pleased with both of them, indicating the great virtue of being dutiful to parents. Disobeying parents is one of the gravest major sins. You must obey your father in what is good and in what does not cause you harm. Bear the hardship to gain his satisfaction, for in his satisfaction lies the satisfaction of your Lord. The Prophet, peace and blessings be upon him, said: "The Lord's satisfaction is in the parent's satisfaction, and the Lord's displeasure is in the parent's displeasure." It is not permissible for your father to accuse your brother's wife of witchcraft without evidence.
