The father returning the proposal in hope of his daughters' salaries

Question:
Sister Salma says: What is the Shaykh’s opinion, and what is the ruling of the Shari'ah in your view, if a father rejects suitors who are, in fact, of good and righteous character, rejecting them from his daughters out of greed for their salaries? Some of these daughters are teachers, and some are school principals, in prestigious positions.

Answer:
The Prophet (peace and blessings be upon him) said: “When there comes to you one whose religion and trustworthiness you are pleased with, then marry him to your daughter, except…” . The guardian who prevents his ward from marrying because of his greed for her salary is one who commits 'udhl (preventing marriage) and commits a major sin among the major sins.
In this case, his guardianship is dropped and passes to the one after him. The daughter must not be prevented from marrying so that her guardian can exploit her, and what he takes on account of this, such as this 'adhl, is forbidden for him and an injustice. It is forbidden and an injustice. So he should fear Allah and hasten to marry off his ward.
And Allah (Exalted and Majestic is He) said: This is a command. The Prophet (peace and blessings be upon him) said: “When there comes to you one whose religion and trustworthiness you are pleased with, then marry him to your daughter” . And this is 'udhl, and 'udhl is preventing a woman from marrying, preventing the woman from marrying a suitable match whom she has accepted. Yes.
