Is it permissible for a girl to choose her competent husband regardless of his nationality and her father's approval? And is there a prayer to improve the morals of a father who chooses from religion what suits his whims?

The guardian (wali) is a condition for the validity of the marriage contract, and this is the view of the majority of scholars. The person most entitled to guardianship is the father. If his unsuitability is proven, guardianship transfers to the next in line, such as the grandfather. Among the legal conditions for the husband are his religiosity and good character. The wife's consent is obligatory, and she cannot be forced into marriage with someone she dislikes. Parents are not permitted to compel their child to marry someone they do not desire. It is advised for someone whose father is in this state to pray for him, seek assistance from some of his colleagues or relatives to reform him, and provide him with booklets and tapes that encourage good character, presenting them to him in a gentle manner.
