Sunan Ibn Majah, Chapter: The Chapters on Gifts

one of the sons of Kab bin Malik, from his grandfather, that his grandmother Khairah, the wife of Kab bin Malik, came to the Messenger of Allah (saw) with some jewelry belonging to her and said, I am giving this in charity. The Messenger of Allah (saw) said to her: "It is not permissible for a woman to dispose of her wealth without her husband's permission. Did you ask Kab's permission?" She said: "Yes." So the Messenger of Allah (saw) sent for Kab bin Malik, her husband, and said, "Did you give Khairah permission to give her jewelry in charity?" He said: "Yes." So the Messenger of Allah (saw) accepted it from her. Daif
