Avoid Suspicion. You Know What I'm Talking About.

O believers! Avoid many suspicions, ˹for˺ indeed, some suspicions are sinful. And do not spy, nor backbite one another. Would any of you like to eat the flesh of their dead brother? You would despise that!1And fear Allah. Surely Allah is ˹the˺ Accepter of Repentance, Most Merciful.

I also read somewhere, in another book about he who always doubts.
