Amr bin Murrah bin 'Abdullah عمرو بن مرة بن عبد الله بن طارق · General Behavior (Kitab Al-Adab)

Avoid suspicion for suspicion is the most lying form of talk. Do not be inquisitive about one another, or spy on one another.

The Prophet (ﷺ) said: When you hear....(Musa's version has): When a man says people have perished, he is the one who has suffered that fate most. Abu Dawud said: Malik said: If he says that out of sadness for the decadence of religion which he sees among the people, I do not think there is any harm in that. If he says that out of self-conceit and servility of the people, it is an abominable act which has been prohibited.
