Sunan Ibn Majah Book 14, Hadith 15

his grandmother Khairah, the wife of Ka'b bin Malik, came to the Messenger of Allah (ﷺ) with some jewelry belonging to her and said, I am giving this in charity. The Messenger of Allah (ﷺ) said to her: “It is not permissible for a woman to dispose of her wealth without her husband's permission. Did you ask Ka'b's permission?” She said: “Yes.” So the Messenger of Allah (ﷺ) sent for Ka'b 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 (ﷺ) accepted it from her.
