Sayyiduna Abu Hadrad al-Aslami (may Allah be pleased with him) said: I came to the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) said: "O Abu Hadrad! How much dowry did you give?" I said: Five uqiyahs. The Messenger of Allah (peace and blessings be upon him) said: "Even if you were scooping (wealth) by the handful from Buthan, you would not have given more than this."
