There is no one in this world who has all the qualities and free from all the faults. Some people may be too fat or too thin. Their mouth may be too big, have large noses or big teeth. Others may be dirty, impolite, shy, cheeky, depressed, bad-tempered, jealous, lazy or selfish. Some women may not be good cooks or talented hostesses. Some people may eat too much or spend lavishly. In brief, everyone is imperfect and no one in this world can be regarded as a perfect being.
Men usually, before marriage, imagine their ideal woman to be devoid of all faults. They ignore this fact that there is no angel-like figure in our universe. These men, once married, find their ideal wives not to be perfect and thus start to point out their faults. They might even regard their marriages as failures and call themselves 'unlucky'.
These men are always moaning and do not even spare the trivial faults of their wives.
Some men exaggerate the faults so much that they always appear before them like high mountains. They occasionally mention these faults to their wives and humiliate them. They might even mention them before friends and relatives.
As a result, the foundation of their marital life starts trembling. The woman becomes depressed and loses interest in her husband and family. She would think it illogical to work in the house of someone who criticizes her. She might even take retaliatory measures.
The man says to his wife: "What a big and ugly nose you have!?" And the woman replies: "It is not as bad as your ugly face and deformed figure!" The man would then say: "Your feet smell foul!" And the woman replies: "Shut up your big mouth!" etc.
A continuation of this conversation opens the door for criticisms and turns the house into a battlefield in which the couple insults and degrades each other .
If they live like this, they would not enjoy their lives ever again, because a house devoid of family love and sincerity, is not a place of comfort.
Moreover, a man who regards himself as unlucky and his marriage as a failure, and a woman who is constantly being humiliated, are both prone to mental disorders and other illnesses.
If the magnitude of their row becomes larger then there is always the danger of divorce and separation. A divorce is not very helpful to either party especially if there are children in the family.
Society does not have much respect for a divorcee. Moreover, a divorce would inflict economic losses on a man, which are not easily repairable. This is especially true if he wants to re-marry, since he would also have to spend money on his second marriage. Furthermore, it is not at all clear that a divorcee is able to find another woman who would live up to his expectations.
Re-marriage would not be easy for him because of his past record. Even if he finds another woman, she would definitely possess certain faults also. She may even turn out to be worse than his first wife. He would then have to cope with her. This is because some men are too proud to confess their shortcomings. It is rare to find a man who is fully satisfied with his second marriage. It has even been seen that some men return to their first wives.
Dear Sir! why should you look at your wife with a view of finding her faults and why do you place so much importance on her trivial defects? Why do you magnify her deficiencies so much so that it causes suffering for you and your family? Have you ever seen a perfect woman? Are you perfect yourself? What are trivial deficiencies worth that you endanger your marriage for their sake?
Be certain that if you look at your wife with a logical and fair view, you would see many good points about her. You look and see that her merits would outweigh her deficiencies.
Islam regards this attitude as harmful and distasteful and thus forbids all from finding other people's faults.
"The Prophet (SA) of Allah stated: 'O you who express to be Muslims by tongue only but faith has not entered your hearts! Do not speak ill of Muslims and do not set out to find their faults (because) whoever picks up fault with others, would be criticized by Allah and even if such a person is at his house, he would be disgraced'."
