Is the husband's father permitted to prevent the wife from giving gifts to her parents, knowing that the husband does not object, his financial situation is excellent, and he himself gives gifts to his family that are four times the value of the gift the wife wishes to present to her parents, and the husband's father's justification for the prevention is saving?

The wife must seek her husband's permission before spending from his money in any way, unless he has given her absolute permission or she knows he approves. If not, she is not permitted to do so. As for the husband's father preventing gifts to the wife's family, this is not justified unless it causes harm to the son's wealth. In that case, the husband must obey his father, and the wife must help her husband in his dutifulness to his father. If there is no harm, there is no justification for the father's action, and the husband should persuade him kindly. Regarding the wife spending from her own private money, the majority opinion is that seeking the husband's permission is recommended, not obligatory. She may donate up to a third or less without the husband's permission according to the Maliki school. It is advisable not to disclose private matters to the husband's father to avoid problems.
