Continuation for the sake of benefit: Types of permissible backbiting, the fourth type

The Shaykh : "And one who openly commits open sinfulness." This is the greatest matter in which Muslims must advise one another. If we see a Muslim associating with a Muslim, or a Muslim woman associating with an open sinner—and how many open sinners there are in our time—because merely for a woman to leave her house displaying her adornment, not wearing the jilbab that her Lord has made obligatory upon her, is open sinfulness and lewdness. This is because she contradicts the clear text of the Noble Qur'an, where the Lord of the Worlds says: . So if we see a believing girl who is modest and has opposed the entire society out of fear of Allah (Blessed and Exalted is He), not caring about the people, men and women, who are open sinners, and yet she associates and socializes with someone who is not like her in her modesty and her covering, she must be warned against associating with her... This warning is the third type, which is not the one who openly commits open sinfulness. Because the third type may not have in their appearance anything that indicates the corruption of their inner self, and yet it is said to their companion: "So-and-so has such and such a description and such and such a characteristic. Beware of her." As for the fourth type: "And one who openly commits open sinfulness," she publicly declares her opposition to her religion and her disobedience to her Lord. This type is subject to backbiting. Why? To warn her, or this type, so that perhaps he may repent and turn to his Lord (Blessed and Exalted is He). There is no backbiting for one who openly commits open sinfulness, and a clear hadith has come regarding this, but its chain of narration is not authentic from the Prophet (peace and blessings be upon him). Its wording is: "There is no backbiting for an open sinner." However, it is a weak hadith, even though its meaning is correct. "And one who openly commits open sinfulness."
