Musannaf Ibn Abi Shayba 13:907

Abu Bakr narrated to us, he said: Yazid bin Harun narrated to us, from Hisham, from al-Hasan, regarding a man who comes to his wife, and they say, "We will not let you go until you give her something." He said: "It is obligatory upon him; he is to be taken to task for it."
