A man who gives another man in marriage and he denies it: what of the mahr?

Al-Zuhri said: If a man sends a marriage proposal on behalf of another man and has the marriage contracted, but the groom later denies it, the woman's right is established against the one who arranged the marriage, and he will have to pay half the dowry.

Concerning a man who wrote to his father or his mawla asking him to arrange his marriage, and he arranged it, but the man then denied it, Amir al-Sha'bi said: If the husband upholds the marriage, it is valid; otherwise this marriage has no standing. And before consummation, no dowry is due from anyone.

Ata said: If a man arranges his father's marriage while the father is absent, and the father is not pleased, the dowry is due from the son; and if the father arranges the son's marriage and the son is not pleased, the dowry is due from the father.
