مَنْ صَمَتَ، نَجَا
Whoever remains silent is saved.

صَمَتَ is a past-tense verb meaning “remained silent,” and نَجَا means “was saved.” In the very compact condition-and-response sentence مَنْ صَمَتَ، نَجَا, the connection draws attention to the risks of harmful speech: silence can be protective when words would cause damage.
The narration does not require silence in every circumstance. Truthful testimony, appropriate help for someone harmed, necessary questions, and constructive advice are valuable forms of speech. The lesson is to distinguish needless or damaging words from words that responsibly serve truth and benefit.
