Passing information between people is not always malicious tale-bearing. Reporting accurate information to the proper person to prevent harm differs from distorting private talk to create hostility.
Example 1: Someone overhears a private conversation and passes on a sentence without context to turn two colleagues against one another. This illustrates the harmful conduct associated with قَتَّاتٌ.
Example 2: A person reports limited, accurate facts to a responsible authority to protect someone from a genuine threat. The purpose is protection rather than discord.
The doubled letter in قَتَّاتٌ gives the word an intensive pattern. The manner and consequences of the speech matter, as well as the speaker’s purpose.
