In Islam, the Mahr (dowry) is one of the rights of the wife, which is entirely hers and is legal for her, unlike the general practice in some countries where the wife does not receive the dowry.
The dowry is the amount of money paid by the young man or by the family of the young man, the future bride. The dowry is of two types:
The first dowry that is paid immediately and represents a more symbolic amount of money. The second dowry, which is a larger amount of money that will return to the wife in case of divorce or death of the husband. This endowment is not provided by the Qur'an but is a traditional practice. Usually, the second dowry remains with the children of the family.
The woman is entitled to the full dowry if the marriage has been consummated or if the husband dies before the consummation. She is entitled to half the dowry if the marriage is dissolved before consummation. But, he is not entitled to the dowry when the marriage is annulled.
The Mahar is the right of the wife, and her father or anyone else is not allowed to take it, except with her approval.
Is it permissible to delay part or all of the Mahar at the time of the marriage contract?
The Mahar is allowed to be given immediately or delayed, or part of it may be given immediately and part of it may be delayed, as agreed by the spouses. There is nothing wrong with that.
This issue depends on what is agreed between the two spouses or between the husband and the woman's guardian. If I agree with something, there is nothing wrong with it, whether it is an immediate payment or a delay.
When I was engaged, other relatives of ours received many gifts, they received the amount of money with gold jewelry, the Koran and incense, bags, cosmetics, perfumes, shoes, materials for dresses, flowers with candy, things for the house, crockery, towels, all kinds of necessities for the house, for her and for her husband. Hand wipes for both. Gifts vary from case to case. Depending on the money that the groom's family has, the bride is also given gifts.
The engagement takes place separately, the women separated and the men separated. I spend separately. The fiancé and the mother with the woman's side come to bring the bride's clothes and engagement rings. Engagement rings can be bought together with the bride and groom. Or each one buys them separately, the fiancée sends the fiancé to bring them to the engagement. At the engagement, they put their finger on each other as a sign that they are husband and wife in front of society. I bought wedding rings with my husband. We put them on our finger at the wedding, a sign that we are husband and wife.
