Advice for those who refuse to marry off their daughters

Question:
The sisters who asked, using the initials (M. N) for their names, say in this question:
Your Eminence, we are sisters from the Eastern Province. Some of us are employees, some are university professors, and some are studying in the advanced university studies program. We have a father—may Allah guide him—who rejects everyone who proposes to us, even though the suitors include qualified men, men of good character, and men committed to obeying Allah. Our father rejects them on the basis of weak excuses that have no authority from Allah. He says that he will not marry us off unless the suitor is from our city, even though he, may Allah guide him, is married to two women from the same city. We ask Your Eminence, Shaykh Abdul Aziz, to advise our father and guide him to the truth in the program *Nur 'ala al-Darb*.
May Allah reward you with good.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful.
Praise be to Allah, and may Allah send prayers and peace upon the Messenger of Allah, and upon his family and his Companions, and upon those who follow his guidance. As for what follows:
It is obligatory for all guardians to fear Allah regarding those under their guardianship and to marry them off when a suitable suitor proposes, whether the guardian is a father, grandfather, son, brother, uncle, or otherwise.
It is obligatory for the guardian to fear Allah and to hasten to marry off the one under his guardianship, whether she is his daughter, his sister, or otherwise. It is not permissible for him to be lax in this matter or to make excuses based on things that have no basis. This is based on the saying of the Prophet (peace and blessings be upon him): and his saying (peace and blessings be upon him): This applies to both men and women. When a woman is proposed to, she must be married off if the suitor is suitable, because that is what best protects her chastity, lowers her gaze, and keeps her farthest from temptation, whether she is a teacher, a student, an employee, or otherwise, and whether she is in need of her salary or not.
The father and others must fear Allah, watch over their conduct before Allah, and beware of wronging a daughter by delaying her marriage. Rather, when a suitable suitor proposes, whether he is from her country, her tribe, or from another country or tribe, as long as he is suitable in his religion, it is obligatory to marry her to him. This is based on his saying (peace and blessings be upon him): He did not say: from your family, from your tribe, or from your country. No, the important thing is the soundness of his character and his religion.
It is not permissible to keep a woman confined for the sake of her salary, or for her to serve him, or for anything similar. Rather, he must marry her off, fear Allah regarding her, and seek someone else to serve him, such as a servant or a wife he marries. As for keeping his daughter or sister confined so that she serves him, or so that he can take her salary, this is injustice. The Messenger (peace and blessings be upon him) said: We ask Allah for guidance for everyone.

The presenter: O Allah, amen. May Allah reward you with good, Your Eminence.
