The Result of This Wrath: Advantages for Both Sides

The Flowers Of Guidance Volume One Coquetry and Coyness of Well-Inclined and Wise Women

Such anger, indeed, is a victory for the husband, because people are mostly unaware of their flaws, and may carry out wrongdoings and negligence in their lives. In such cases, it is incumbent upon their friends to inform them of those flaws. All the ethical leaders have mentioned that a friend is one who reveals the shortcoming of another, not one who pretends to admire the flaws of another person. A friend who admires our shortcomings is, in fact, our enemy, and a friend who points out our flaws is the kindest of friends.

As the Sheikh-e-Ajal, Saadi (Peace be upon him) denotes:

When a friend flatters you, it is hurtful
When he magnifies your flawed attitude as good, it is hurtful

Where is my enemy who is so artful
In letting me know all my flaws as they are, for which I am so grateful

A truth-seeking individual does not get offended when someone mentions his flaws. A simple example:  imagine that a person leaves the house one morning, while there is a defect in his clothes that he did not notice. If a friend notifies him right away about the defect, he will be able to correct it without delay. However, if his friend or anyone else does not inform him, thousands are going to see him all day in this situation, and it will create a feeling of embarrassment and contempt in him. Which is better? When a friend informs us of our flaw instantly, we will attempt to correct and rectify it.
