«اِلظَّنِّ السَّو يِوَدِّي جَهَنَّمْ»

The saying condemns thinking ill of others with a severe religious warning. Suspecting people of bad intentions, especially without grounds, is portrayed as a moral danger grave enough to lead a person to Hell. The image of Hell gives the warning its force rather than merely naming an ordinary setback.

In use, it rebukes a person who jumps to unfavorable conclusions about others. It urges caution before imputing motives or wrongdoing, presenting baseless suspicion as a fault of the suspicious person. The wording is condemnatory, not simply a prediction of tension or unhappiness between people.

Said to someone who is reading bad intentions into another person's actions without proof, to urge restraint and fairness. It suits moments of gossip, jealousy, or quick accusation, and works as a gentle warning or rebuke.
