Chofetz Chaim Daily 12 Nissan 9:3 Asur to relate praise that may cause damage. Eg. Telling that ploni hosted you or lent you money, etc. This can cause ploni harm bc others will now demand the same. Asur to say something that can be mistaken for LH. 9:4 Asur to live among baalei LH. Asur to listen even if not intending to believe. One who finds himself in a group of LH speakers must protest even if you know they won’t listen.
Chofetz Chaim Daily 11 Nissan 9:1 Asur to speak AVAK LH which is a negative inference eg. “who would think ploni would end up so good?”, “its better we dont talk about ploni” Praising ploni in presence of an enemy or excessive praise to any listener is also avak LH. 9:2 All praise is asur in public, except about universally accepted Tzaddik.
Chofetz Chaim Daily 10 Nissan 8:13 Asur for anyone to BELIEVE LH regardless of who the subject is, except for apikores & informers etc. 8:14 Likewise, it doesn’t matter who its heard from, even parents and family members. One is responsible for the behaviors of his household. He should therefore restrain them from LH and set a positive example.
Chofetz Chaim Daily 6 Nissan 8:5 Mitzvah to say LH about a known apikores (one who denies anything of written or oral law) 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. 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 apply for a rasha. Here again the Halachos are different for a Tinok Shenishba.
Chofetz Chaim Daily 7 Nissan 8:8 Some permit LH about baalei machlokes to cause those at fault to stop fighting, IF 1. you have good intentions & not hate 2. no other way to stop it 3. you’re certain this party is the guilty one. 8:9 There is a cherem against saying LH about dead people, especially Torah scholars & their teachings.
