Hadith 210 values protecting someone’s dignity; Hadith 212 warns against withholding needed knowledge. They are not contradictory. The first concerns needlessly exposing a private failing; the second concerns refusing reliable knowledge when guidance is appropriately needed. Hadith 213 adds the duty not to mislead someone deliberately.
Example 1: Do not publicize a friend’s irrelevant past mistake.
Example 2: If a child is at risk, necessary reporting to a responsible person can protect them.
Example 3: When you possess relevant, reliable knowledge, provide a careful and useful answer.
Truthfulness, confidentiality, and goodwill work together when each person’s legitimate rights are respected.
