Amr b. Shu'aib on his father's authority said that his grandfather reported The Messenger of Allah (ﷺ) said:
A woman who marries on a dower or a reward or a promise before the solemnisation of marriage is entitled to it; and whatever is fixed for her after solemnisation of marriage belongs to whom it is given. A man is more entitled to receive a thing given as a gift on account of his daughter or sister (than other kinds of gifts).
