There is tremendous power in learning from the Sefer Chofetz Chaim each day. In this crucial time, we’re going to help encourage that effort with a few halachos a day using Sefaria’s translation (https://www.sefaria.org/Chafetz_Chaim).
-Part One, The Prohibition Against Lashon Hara, Principle 2, Seif 3
There are some who say that if one speaks demeaningly of his friend before three, even though he certainly transgresses the issur of lashon hara, as mentioned before, still, if one of the three who heard this thing told it thereafter to others, he does not thereby transgress the issur of lashon hara, by reason of the fact that if three know of it, the thing has been heard and become known by all, for “Your friend has a friend, etc.,” and the Torah did not forbid as lashon hara something which is bound to be known. And [this is so] only if he relates it by chance; but not if he intends to spread it and to publicize it more.
Even if he does not relate it in the name of the one who told him [so that there is no rechiluth], but casually, to the effect that such and such was heard about Ploni, still he does not escape the issur of lashon hara.
-Part One, The Prohibition Against Lashon Hara, Principle 2, Seif 4
And even our heter [to repeat this to another] where there is no intent to publicize it, applies only to the first hearer, who himself heard what Reuven said about Shimon in the presence of three. But he who heard it from him is forbidden to go thereafter, on the authority of his having been told that he heard it in the presence of three, and to tell another of the taint he heard attributed to Shimon, even if he does not mention who it is that purveyed this slander against Shimon — unless the thing were publicized and became known to all. And this applies not only when this second hearer does not himself know whether the allegation itself — that Reuven slandered Shimon — is true, in which instance he certainly is forbidden to believe him [his informer] that Reuven transgressed the issur of lashon hara. But even if he knows himself that Reuven spoke demeaningly of Shimon, but he does not know if he did so in the presence of three, in spite of this, he is forbidden to rely on his words to this effect, and we fear that perhaps it was not in the presence of three and that it is not bound to become public knowledge, wherefore he [the second hearer] is forbidden to tell it to anyone.
