Is the father considered sinful if he does not contribute to the marriage expenses of his daughter, who has severed ties with him, rejected his legal financial support, and did not ask him for help with her marriage?

This question addresses the father's duty towards his daughter in marriage, the condition of the guardian (wali) in marriage, and how to deal with a daughter's estrangement from her father.

Firstly: A father must provide for his daughter and marry her off if a suitable suitor proposes and he is able to do so.

Secondly: Marriage is not valid except with a guardian (wali), and the closest guardian is the most entitled. If a more distant guardian contracts the marriage in the presence of a closer guardian, and without a legitimate excuse or authorization, then the contract is invalid.

Thirdly: The father should review the reason for the estrangement between him and his daughter and remove the causes if they stem from him. He should remind her of the obligation to honor him if the problem is from her side. If the daughter insists on marrying a suitable man, the father can appoint someone to marry her off. Also, the father is not obligated to contribute to her marriage expenses if she has estranged herself from him and refused his provision.
