If you are far from Allaah, then yes it is, but the more fearing of Allaah you are, the better marriage is because a good woman would not burden her potential husband financially, and the Husband in turn, won't have unrealistic expectations either. I know of many good Muslim women, some of my female cousins, who took humble Mahr's [a few thousand at the most] and have good, marriages, Alhamdulilah.
