What is the way to convince a father to approve his daughter's marriage to the first suitor, despite the father's rejection of him after a richer person proposed, and the daughter's approval of the first suitor?

If you are a person of good character and religious commitment, the girl should remind her father of the hadith: "If someone whose religious commitment and character you approve of comes to you seeking marriage, then marry him. If you do not do so, there will be tribulation on earth and widespread corruption." She should inform him of her desire to marry you, and that his prevention of her marriage to you is considered an unlawful act of 'adhl (unjust withholding of marriage), and that the noblest of people in the sight of Allah are the most pious among them. She should seek the help of righteous people. If that does not work, she should take her case to the Sharia court so that the judge may compel him to marry her, or the judge himself may marry her off. However, if you are not satisfactory in terms of religious commitment and character, the girl should not create a problem between herself and her father. Both parties should choose a person of religious commitment, for a woman is married for four reasons, so win the one who is religious, and a man is sought for his religious commitment and character, and by this, a happy marital life will be achieved.
