Ibn Abi al-Ajfa' narrates from his father that Sayyiduna Umar (may Allah be pleased with him) said: "Do not give excessive dowers to women." He mentioned it in agreement with the hadith of Hammad, that a man gives an excessive dower and then says: "Because of you I was burdened, even with the strap of the waterskin," and he holds it against her as a fault.
