سنن أبي داود

AbulAjfa' as-Sulami said: Umar (Allah be pleased with him) delivered a speech to us and said: Do not go to extremes in giving women their dower, for if it represented honour in this world and piety in Allah's sight, the one of you most entitled to do so would have been the Prophet (ﷺ). The Messenger of Allah (ﷺ) did not marry any of his wives or gave any of his daughters in marriage for more than twelve uqiyahs.
