'Umar b. al-Khattab said:
Do not go to extremes in giving women their dower, for if it represented honour in this world and piety in Gods sight, the one of you most entitled to do so would have been God's Prophet. I am not aware of God’s Messenger marrying any of his wives or giving any of his daughters in marriage for more than twelve uqiyas.
Ahmad, Tirmidhi, Abu Dawud, Nasa’i, Ibn Majah and Darimi transmitted it.
