"When the Messenger of Allah conquered Makkah, he stood up to address (the people) and said in his Khutbah: 'It is not permissible for a woman to give (a gift) except with her husband's permission.'"
Sunan an-Nasa'i Book 34, Hadith 39
← Previous Hadith "It is not permissible for a woman to give a gift from her wealth, once her husband has marital authority over her." This is the wording of (one of the narrators) Muhammad.

Sunan an-Nasa'i Book 34, Hadith 38 Next Hadith → "The delegation of Thaqif came to the Messenger of Allah, bringing a gift with them. He said: 'Is it a gift or charity?' If it was a gift it would be for the sake of the Messenger of Allah and to have their needs met, and if it was charity then it would be in the cause of Allah. They said: 'It is a gift.' So he accepted it from them, and sat with them, and they asked questions, until he prayed Zuhr with 'Asr."
