Qutayba bin Sa'id bin Jamil قتيبة بن سعيد بن جميل · The Book of 'Umra

"Abu Az-Zubair informed me that he heard Jabir saying: 'The Messenger of Allah said: "Whoever is given something on the basis of 'Umra it belongs to him for the rest of his life and after he dies."'"

"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.'"
