Imam al-Sha'bi (may Allah have mercy on him) said: Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) addressed the people, praised and extolled Allah Almighty, and said: Do not give excessive dowers to women. If I learn that anyone has given more as dower than the Messenger of Allah (peace and blessings be upon him) gave, or than was given to him, I will deposit the excess in the treasury (bayt al-mal). Then he came down from the pulpit, and a woman from nearby said: O Commander of the Faithful! Is the Book of Allah more entitled to be followed, or your word? Sayyiduna Umar (may Allah be pleased with him) said: The Book of Allah; but what has happened? She said: You have just forbidden people to give excessive dowers to women, whereas in the Book of Allah it says: "And you have given one of them a heap of treasure (qintar), then do not take anything from it." [Surah al-Nisa: 20] Sayyiduna Umar (may Allah be pleased with him) said: Everyone has more understanding than Umar (may Allah be pleased with him); he said this two or three times. Then he went back to the pulpit and said to the people: I had forbidden you to give excessive dowers, but a man may give from his wealth as much as he wishes.
This is munqati' (its chain is broken).
