Did I err in publicly correcting — on the same platform — a published piece of information stating that the Messenger, peace and blessings be upon him, used to congratulate non-Muslims on their holidays, by citing authentic hadiths and warning against lying about the Prophet, knowing that the person who published the information did so for everyone to see, and I was blamed with the remark that "advice in public is a disgrace"?

Advice, in general, is a religious duty, particularly concerning dealings. The original principle is that it should be private, out of consideration for the discreetness of the advised. However, if the public interest necessitates its disclosure, especially regarding matters of doctrine and religious law, then it becomes obligatory to announce it. The Prophet, peace and blessings be upon him, gave advice both privately and publicly, and sometimes singled out individuals, depending on the situation and the prevailing interest. Therefore, if a reprehensible act is openly committed, or widespread, or if a scientific error is publicized, it is obligatory to denounce it publicly, while considering the identification of the perpetrator based on what serves the greater good. Consequently, there is no blame upon one who gives advice publicly in such cases, provided they adhere to the etiquette of dialogue.
