To what extent does the legal and social right of a girl's father extend in requesting half of the marital apartment be owned by his daughter before the marriage contract, given that the young man paid the full price of the apartment and furnished it?

The wife's father should not impose burdensome conditions, for the Prophet, peace and blessings be upon him, said: "The most blessed of women are those who are the least burdensome." Guardians should obey the Prophet's command to marry off those whose religion and character you approve. However, if the wife or her father stipulates conditions and you agree to them, you must fulfill them, for the Prophet, peace and blessings be upon him, said: "The most deserving of conditions to be fulfilled are those by which you make intimacy lawful." Although it is better not to be excessive in conditions. If the wife is of good character and religion, then you should be keen on her and respond to her conditions if they are within your capacity. If she is otherwise, or if she stipulates something beyond your capacity, then you should leave her.
