The Messenger of Allah ﷺ said, "Whatever a woman is married for as a dowry, gift, or promise made before the marriage contract is finalized belongs to her, and whatever is given after the marriage contract is finalized belongs to the one to whom it was given. The most deserving thing for which a man is honored is his daughter or his sister."
قال رسول الله ﷺ: أيما امرأة نكحت على صداق أو حباء، أو عدة قبل عصمة النكاح فهو لها، وما كان بعد عصمة النكاح فهو لمن أعطيه، وأحق ما أكرم عليه الرجل ابنته أو أخته.
Reported by Abu Dawud (2129), Ibn Majah (1955), Nasai (3353), and Ahmad (6709), all from the hadith of Ibn Jurayj, who said, Amr bin Shuayb said, from his father, from his grandfather, and he mentioned it. Bukhari and others said, "Ibn Jurayj did not hear from Amr bin Shuayb." However, Hajjaj bin Artah corroborated him, narrating it from Amr bin Shuayb with his chain, with this wording, "Whatever is given to make lawful a woman's private parts, whether a dower or provision, belongs to her, and whatever her father or brother or guardian is honored with after the marriage contract is concluded belongs to him, and the one most deserving to be honored by a man is his daughter or his sister."This was reported by Bayhaqi (7/248), and there is some discussion regarding Hajjaj bin Artah. However, taking the two chains together, the hadith becomes hasan.As for its meaning, some scholars said this hadith should be understood as meaning that if the guardian stipulates wealth for himself apart from the dower, it belongs to him, while the dower itself is a right belonging to the woman. It has been narrated that Ali bin Husayn married off his daughter to a man and stipulated for himself ten thousand dirhams.Among customs and common practice is the exchange of gifts between the two parties, and so long as this does not involve invalid stipulations, there is no harm in it. This includes a man's outfitting of his daughter with household items, utensils, and the like, as comes in the hadith that follows.
