It is wise for the man and woman to have a wedding to celebrate their spiritual union and this cost to be equally paid for by both parties. The woman can use her dowry money if she has no money of her own.
By a woman also investing into the relationship she is less likely to leave. But a man should only marry a virgin of his own people. If she is not a virgin he should keep her as a girlfriend. A man should give a wife a dowry of either property, land, gold, money or a business.
