What is the ruling regarding a fornicator who demands money from his children to commit fornication with, shows no regard for the sanctity of his daughters, and has caused them to remain unmarried?

We advise turning to Allah Almighty and asking Him to facilitate marriage and guide the father. There is no harm for a woman in seeking a righteous husband. Accusing the father of adultery without proof is a serious matter that requires repentance. Whoever sees the father committing a sin should advise him with gentleness and kindness, explain the error of his actions, and advise him to marry instead of taking a mistress. If he asks people for money without need, he should also be advised in this regard. The child must comfort his father with his money and spend on him if he is in need. The father may take from his son's money what he needs, without extravagance or harming the son. However, if he will spend what he takes extravagantly or cause harm to the son, then the father should not be allowed to take from his money. It is necessary to deal with the father with wisdom and tact.
