Is a wife obligated to fulfill her husband's desire not to prolong prayer or recitation of the Quran to avoid his anger, knowing that he prays and fasts, but dislikes seeing her do so, to the extent that he told her: "This Quran is a curse upon you"?

If a woman performs the obligatory duties (fara'id), there is no harm in her engaging in voluntary acts of worship (nawafil), and she will be rewarded for them, provided that this does not lead to neglecting her husband's rights. This is based on the Prophet's (peace be upon him) saying: "Indeed, your Lord has a right over you, and your soul has a right over you, and your family has a right over you, and your wife has a right over you. So give each one who has a right, his right." If she fulfills her husband's rights, then he has no right to prevent her from performing voluntary acts of worship, because obedience to the husband is in what is good (ma'ruf), and preventing her from worship without any harm is not considered good. However, if she falls short in her husband's rights because of her voluntary acts, then she must limit herself to what allows her to fulfill his rights, for voluntary acts are not prioritized over obligatory ones, and the husband's right is an obligation. As for the husband's statement, "This Quran is a curse upon you," it is impermissible, and he must seek forgiveness, for the Quran is a mercy and a healing, not a curse.
