Islam is the only major religion that puts a cap on polygamy, limiting the number of a mans wives to four—provided the husband can do justice to all of them. Although some religions, such as Catholicism for instance, puts a cap on polygamy all together, or even serial monogamy, allowing one spouse until death does them apart, not even accepting divorce. According to the teachings of Islam a Muslim man should have a valid reason and have to get permission from his existing wife (without any force) if he requires to marry again. Islam vehemently abhors any intimate relationship outside the bond of marriage. There is no external sign to show his status as a husband, unless he adopted the tradition of wearing a wedding ring. Hinduism
A Hindu husband traditionally takes his wife to his home. He is expected to provide for her and to prove his abilities to do so. The marriage in Hinduism is a relationship for Seven births (सात जन्मों का सम्बन्ध). Before 1951 there was no divorce allowed in Hindu marriage. In modern times once again after 1951, equal rights for women through society and law jurisdiction is given. In Hinduism, based on the different regions, marriage process is observed differently with the same Saat Pheras around agni kund (light pyre) to be taken to become a husband and wife. The Encyclopædia Britannica mentions that "In Hindu law, the male members of a joint family, together with their wives, widows, and children, are entitled to support out of the joint property."
A husband is a male in a marital relationship, who may also be referred to as a spouse. The rights and obligations of a husband regarding his spouse and others, and his status in the community and in law, vary between societies and cultures, and have varied over time. In monogamous cultures, there are only two parties to a marriage, which is enforced by laws against bigamy and polygamy. Traditionally, the husband was regarded as the head of the household and was expected to be the sole provider or breadwinner, a role that continues in some cultures (sometimes described as paternalistic). Today, a husband is not necessarily considered the breadwinner of the family, especially if his spouse has a more financially rewarding occupation or career. In such cases, it is not uncommon for a husband to be considered a stay-at-home father if the married couple have children. The term continues to be applied to such a man who has separated from his spouse and ceases to be applied to him only when his marriage has come to an end following a legally recognized divorce or the death of his spouse. On the death of his spouse, a husband is referred to as a widower; after a divorce a man may be referred to as the "ex-husband" of his former spouse. Origin and etymology
The term husband refers to Middle English huseband, from Old English hūsbōnda, from Old Norse hūsbōndi (hūs, house + bōndi, būandi, present participle of būa, to dwell, so, etymologically, a householder).
