one thing to correct here that is Islam doest not give right of dowry to women.in fact, there is no concept of dowry in Islam because sole responsibility to maintain house is of husband so he provide those thing to furnish such things which we calls a dowry and gives to our sisters and daughters. this is typical hindu tradidion and not muslim, on the contrary, Islam enables the righ of dower for a women at the time of marriage which is essential element for the contract of marriage and consideration for women for the contract of marriage.
