Benefits and Issues: It is not permissible to publicize the faults of a Muslim brother; however, one should certainly advise him in an appropriate manner, quietly, so that he may reform himself. Furthermore, it is obligatory to wish well for him in every way, whether he is present or absent.

Abu Hurairah (RAA) narrated that the Messenger of Allah (ﷺ) said: “Every believer is the mirror of his brother.” Related by Abu Dawud with a good chain of narrators.
➋ The mirror only informs the one looking into it; it does not gossip about him in front of others.
➌ The mirror only shows as many faults and flaws as are actually present in the appearance of the one looking into it; it does not add or subtract anything from itself, and it presents them in his presence, not mentioning them in his absence or behind his back. In the same way, a believer should mention his brother’s faults in his presence, not in his absence, and only as many faults as are truly found in him, without any addition or omission from himself.
➍ Even when the mirror is broken into pieces, each piece still shows the same faults of the one looking into it as are actually present. Similarly, even if a believer becomes displeased with his brother, he should only mention as many faults as are truly found in him.
➎ The mirror does not lose its essence even when broken; likewise, a believer should not lose his own essence. And the other believer should consider being alerted to his faults as sincere goodwill and genuine sympathy for himself.
