«مَطْرَحْ مَا تِطْلَعِ الْكِلْمَهْ تِطْلَعِ الرُّوحْ»

The saying ties speech directly to survival. At the very spot where a word leaves the mouth, the soul can leave the body; "the soul comes out" is an idiom for dying, so the danger is to life itself, not mere embarrassment. What someone says may bring ruin back on the speaker.

In practice it urges restraint and discretion. Before speaking, a person should weigh whether the words could provoke anger, betray a secret, or invite retaliation. Silence or caution is often the safer path when stakes are high.

Suitable as a warning to someone about to speak rashly, or as a reflection after careless talk has caused trouble. It fits situations where discretion protects a person from serious, even deadly, consequences, and should not be used for trivial slips of the tongue.
