Men should have freedom in their business and associations in order to be able to work and progress in a way suitable to them. If men are restricted in their activities, then they will not be comfortable. A wise woman would not interfere with the affairs of her husband. She should not monitor his movements; because she should know that by denying him the freedom he needs and by trying to control his activities, he may react severely.
Wise and experienced men do not need to be controlled. Such men always act wisely; they cannot be deceived; they know both their friends and their foes. However, there are men who are simple; they can easily be deceived and would easily be influenced by others.
There are people who are impostors and are lying in wait for simple men. The impostor, though pretending to be a good-doer, traps the man and draws him towards corruption. The corrupt society and the unyielding nature of humans does not help the situation. The simple man may not realize his situation for a while, but one day he wakes up and finds himself deep in a trap from which there is not any escape.
If you look around yourself, you see tens of such unfortunate people. Perhaps none of them intended to fall in the trap or become corrupt, but through their own simplicity, ignorance, and unthoughtfulness , they are now preyed upon by the corrupt in society.
On this account, the simple men need to be taken care of. By monitoring their activities, the wise and well-wishing people would be doing them a great service.
The best people for this task, however, are the wives of these men. A wise and clever wife is able, through a benevolent and wise attitude, to achieve the greatest of the tasks regarding her husband. Such women, however, should remember not to directly interfere with the affairs of their husband, or to tell them the "do's" and the "don'ts". The reason for this is because men mostly do not like to be treated as tool in the hands of others; otherwise they may react sharply. But a wise woman would monitor her husband's activities and watch his associates indirectly without his knowledge.
It also happens that some men, some times, come back home later than usual. If this is the case and the number of the late arrivals to home are within an acceptable limit, then there is no need to worry, because men are sometimes engaged in certain unexpected events which they try to pursue after their work. However, if the number of late arrivals exceeds the accepted limit, then his wife should make an effort to investigate. But investigation is not easy; it requires patience and wisdom; one must avoid anger or protest. The wife should first of all talk to him softly and kindly. She should ask him why he came home later than the day before and where he had been. She should pursue the matter wisely and patiently at different times and on different occasions. If she finds out that he comes back home late because of his work or attends scientific, religious, and moral meetings, then she should leave him alone. If she feels that he has found a new friend, she should find out who he is. If his new friend is a well-mannered person with a clean record, then she should not worry. It is even recommended that she encourages him in his new friendship, because a good friend is a great blessing.
If you feel that your husband is going astray or that he associated with corrupt and unworthy people, then you should stop him immediately. A woman in this situation has a great responsibility. The slightest mishandling of the situation, through carelessness. may shatter their family life. This is a situation where the wisdom and cleverness of some women can become useful and apparent. One should remember that rows or arguments are not the solution and they may result in the exact opposite. A woman, who experiences this event, has two tasks to achieve:
(a) First she should assess the situation at home; and should examine herself and her attitude. She must find out the reason for her husband's behavior. She should fairly judge why he has grown cold towards his family and gone astray. She may find that her own attitude had been the cause; or perhaps she had been the cause; or perhaps she had been indifferent to his desires for food, her looks or the affairs of the house. Such matters draw men away from home. They may then pursue outside deviant activities in order to forget their problems.
The wife can ask her husband about his problems and try to help solve them. If a woman corrected herself and changed the house according to his desires, then she could be hopeful that her husband could be drawn back to his family and that he would avoid corrupt places.
(b) Secondly ,she should show him as much kindness as possible. She should advise him and remind him of the grim consequences of his deeds. She should even cry and beg him to give up his bad companions. She must say to him:
"I love you from the bottom of my heart. I am proud of you. I prefer you to all things and I am ready to devote myself to you. But I am saddened by one thing; why should a man, like you, have these kinds of friends; or attend that kind of a party? Such deeds are not suitable for you. Please give them up"
The wife must continue this attitude until she conquers the heart of her husband.
It is possible that the husband is used to unworthy habits and that he would not be influenced easily, but the wife should not become disappointed. She should pursue her goal with greater strength and patience.
Women have great power and influence over men. She is able to do whatever she wills if she puts her mind to it. If a woman decides to save her husband from the filth of corruption, she can do it. There is an eighty per cent chance of success, provided she acts wisely. Anyway, she must not use violence or a harsh attitude, unless she sees that there is not any result from being kind and gentle to him. Even then she must quarrel, leave home or use any other way in as kind a way as possible and not revengefully.
Yes, looking after one's husband is the duty of every wife. It is a difficult duty and that is why the Prophet (SA) of Islam stated: "The Jihad of a woman is to take care of her husband well."
