Before forwarding a report that may affect someone's reputation, property, or safety, verify it. An unattributed recording, forwarded message, or repeated allegation is not automatically reliable evidence.
Example 1: Do not repost an accusation against an institution without checking a trustworthy source.
Example 2: Confirm a report of illness or an accident through reliable channels before speaking to others.
The word كُلِّ in بِكُلِّ مَا سَمِعَ means “every.” The unselective repetition of everything heard is the central danger identified here.
