Musannaf Ibn Abi Shaybah

Hazrat Zuhri says that if a man sent a marriage proposal on behalf of another and the marriage was conducted, but later the groom refused, then the woman's right will be established upon the one who arranged the marriage, and half of the dowry will have to be given.

Hazrat Aamir says that if a person wrote a letter to his father or guardian asking him to arrange his marriage, and they arranged the marriage, but he refused, then regarding this Hazrat Sha’bi used to say that if the husband maintains the marriage, it is fine, otherwise this marriage has no validity. And before the consummation of marriage, no dowry (mahr) will be obligatory on anyone.

Hazrat Ata says that if a person arranged the marriage of his father while the father was not present, then if the father does not consent, the dowry will be obligatory upon the son. And if the father arranged the marriage of the son and the son does not consent, then the dowry will be obligatory upon the father.
