22. This verse enunciates a fundamental principle. Impure men are a fit match for impure women and pious men are a fit match for pious women. It never happens that a man is good in all other aspects but is addicted to a solitary vice. As a matter of fact, his very habits, manners and demeanor, all contain a number of evil traits, which sustain and nourish that single vice. It is impossible that a man develops a vice all of a sudden without having any trace of its existence in his demeanor and way of life. This is a psychological truth which everybody experiences in the daily lives of the people. How is it then possible that a man who has all along lived a pure and morally clean life, will put up and continue to live for years in love with a wife who is adulterous? Can a woman be imagined who is an adulteress, but she does not manifest her evil character through her talk, gait, manners and deportment? Is it possible for a virtuous man of high character to live happily with a woman of this type? What is being suggested here is that people in future should not credulously put their belief in any rumor that reaches them. They should carefully see as to who is being accused and on what account and whether the accusation fairly sticks on the person or not. And when there exists no trace of evidence to support the accusation, people cannot believe it just because a foolish or wicked person has uttered it.
Some commentators have interpreted this verse to mean that evil things are for the evil people and good things for the good people. The good people are free from the evil things which the wicked people utter about them. Some others have interpreted it to mean that evil deeds only go with evil people and good deeds with good people. The pious people are free from the evil deeds which the wicked people ascribe to them. Still others interpret it to mean that evil and filthy talk is indulged in only by the evil and filthy people and good and pious talk only by the good and pious people. The pious people are free from the sort of talk that these mischievous people are indulging in. The words of the verse are comprehensive and can be interpreted in any of the three ways, but the first meaning that strikes the reader is the one that we have adopted above and the same fits in more meaningfully with the context than others.
