Who is Responsible for the Dowry if a Man Marries Off His Minor Child?

Hazrat Shurayh says that if a person arranges the marriage of his minor child, it is permissible. However, when the child reaches maturity and gives divorce, then half of the dowry will be obligatory upon the child's guardian.

Hasan says it will be obligatory on the Mahram child.

Hazrat Sha’bah says that I asked Hazrat Hakam and Hazrat Hammad about a person who arranges the marriage of his minor child: upon whom is the dowry (mahr) obligatory? Hazrat Hakam said that the dowry is obligatory upon the boy. Hazrat Hammad said that it is obligatory upon the father. It is narrated from Hazrat Qatadah that Hazrat Ibn Umar (may Allah be pleased with them) said that the dowry is obligatory upon the one for whom you arranged the marriage, i.e., the boy.

16775 - Hammad said: It is upon the father.

16776 - And Qatadah said: Ibn Umar said: It is (upon) (1) the one to whom you have married her, meaning the dowry is upon the son (2).

Hazrat Sha'bi says that in this case, the dowry is obligatory upon the father.
