Abdullah bin Amir bin Rabi'ah (may Allah be pleased with them both) narrates from his father that a woman married for (a dowry of) two sandals. She was brought to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Are you content with just two sandals?" She said: Yes. So he (peace and blessings be upon him) permitted it.
