There is no such thing in Shari`ah as sham marriage (on paper). The sin is further compounded if it is done in order to do something that is prohibited, such as one who uses it to avoid giving people their rights or paying debts to them, or if a woman uses it to get help given to divorcees by a state or institution, or so that she can live in a non-Muslim state where it is not permissible for her to reside, and other invalid, forbidden aims.

Allah has permitted a Muslim man to marry a Jewish and Christian woman on condition that they are chaste and avoid zina and that the husband will then have wilayah over her.

1- The basic principle with regard to the conditions stipulated by both partners in the Islamic marriage contract is that it is a valid condition that must be fulfilled, and it is not permissible to break it. 2- If a wife stipulates that her husband should not take another wife, this is permissible. If the husband breaks this condition, his wife does not become divorced as a result of that, rather she has the right to annul the marriage.
