Chofetz Chaim Daily 17 Kislev 10:7 You don’t have to rebuke the perpetrator (third condition ibid) if you’re sure he won’t accept it. But then you must spread to at least 3 people at a time, so they won’t think you’re going behind his back. 10:8 If the perpetrator is dangerous, then you may say it to less than 3 people.
Chofetz Chaim Daily 16 Kislev 10:5 Mutar to defame someone who spoke LH BUT only if the subject is aware of it. Otherwise it will lead to rechilus. 10:6 Even if the subject isn’t aware, mutar if it will create a preemptive benefit. Now people won’t believe the LH rumor that the speaker is trying to spread.
Chofetz Chaim Daily 15 Kislev 10:3 Continued from yesterday. Only mutar if speaker himself isn’t guilty of the same crime. 10:4 Considered l’toeles if purpose is to defame sinners. Asur to tell people who don’t think the injustice was wrong, because it will bring to rechilus. In scenarios that LH is mutar, it is a mitzvah to say. If asur, asur period.
Chofetz Chaim Daily 13 Kislev 9:5 Mitzvah to restrain even your young children from LH so they’ll get into the habit. 9:6 Asur to repeat private matters heard from a friend.
*A Tinok Shenishba, which means someone who wasn’t educated with a Torah education, or someone who didn’t have a stable youth, is considered “Amcha” and one cannot believe LH about him.
Chofetz Chaim Daily 5 Kislev 8:3 Asur to say LH about a child if it will put him in a bad light or cause him damage. 8:4 Asur to say LH about an am haaretz. Saying LH on a scholar can often be in the category of mivazeh Talmid Chacham which is a terrible sin. Someone who’s a Rav and toils in Torah is considered a Talmid Chacham.
Chofetz Chaim Daily 6 Kislev
8:5 Mitzvah to say LH about a known apikores* (one who denies anything of written or oral law)
8:6 If its a rumor, you can suspect and stay away, but do not believe it until you see it yourself or otherwise verify it. 8:7 Same laws above 8:5 apply for a rasha. Here again the Halachos are different for a Tinok Shenishba.
*The Poskim say that a Tinok Shenishba has a Halacha of a regular Jew and no LH should be said about him, unless it is LeToeles with all the conditions.
