Is it permissible to leave one's wife in her country and return to work abroad for a year, given the inability to bring her along due to high living costs, and the fear of harm to one's religiosity if one were to remain alone?

It is permissible for a husband to be absent from his wife for a period not exceeding six months, unless with her permission and consent. He must protect her and safeguard her honor and dignity from anything that might tarnish them. If the wife remains in her family's home without intermingling with those she is not permitted to intermingle with, and she agrees to this, then there is no impediment to the husband traveling away from her, even if it is better for him to take her with him. It is advisable to hasten marriage for those who are able; if one is unable, then one should fast and resort to other means that help in lowering the gaze and preserving one's chastity. One should choose a spouse of piety and good character.
