The law of dowry is obligatory as stated in the Ash-Shafi'i School of thought which defines dowry as something that is obligatory because of marriage or the legal fulfillment of the right to sexual intercourse, because of forced deprivation of the right to sexual intercourse on the part of the husband, or because of khulu' and testimony. So, what is required from men for women is called dowry. Furthermore, the term dowry includes those required because of a valid marriage and those required because of sexual intercourse, whether in a broken, questionable or forced contract.
