Sa'id bin Abi 'Aruba سعيد بن أبي عروبة · The Book on Marriage

The Messenger of Allah said: "Whichever woman married without the permission of her Wali her marriage is invalid, her marriage is invalid, her marriage is invalid. If he entered into her, then the Mahr is for her in lieu of what he enjoyed from her private part. If they disagree, then the Sultan is the Wali for one who has no Wali."

The Messenger of Allah said: "The matron has more right to herself than her Wali, and the virgin is to give permission for herself, and her silence is her permission."

Ibn Abbas said: "Mut'ah was only during the beginning of Islam. A man would arrive in a land that he was not familiar with so he would marry a woman for the extent of time that he thought he would remain there. So his Mut'ah was upheld and his case was fine until the (following) Ayah was revealed: Except their wives or what their right hands possess. Then every private part other than those became unlawful."

"The Prophet prohibited marrying a woman along with her paternal aunt or along with her maternal aunt."
