Does relaying news and topics related to betrayals, adultery, or sexual matters from websites or news to colleagues make me one of those who delve into people's honor or accuse chaste women?

The ruling on transmitting hadiths about tabarruj (ostentatious display/improper adornment) and ikhtilat (unrestricted mixing of genders) varies according to the intention and method. It is permissible to transmit them with a good intention, such as teaching a religious ruling or warning against sins, provided that one adheres to Islamic etiquette and alludes to what is shameful to state explicitly. However, if it lacks a righteous intention or an appropriate method, it is disliked (makrooh) and may even be forbidden (haram) if accompanied by a bad intention, such as inciting desires. This is not considered slander (qadhf) as long as you are speaking about an unknown person.
