Musannaf Ibn Abi Shaybah 18289 — A woman providing the mahr

Yahya bin Abi Kathir (may Allah have mercy on him) said: A case was brought to Sayyiduna Ali (may Allah be pleased with him) in which a woman had married a man on the condition that the dowry would be her responsibility and that the right of separation and of intercourse would also be with her. Sayyiduna Ali (may Allah be pleased with him) said: You have opposed the Sunnah and made one who is not fit for it responsible for the matter. The dowry is upon you, and the right of intercourse and separation is with you, and that is the Sunnah.
