To disclose the secrets of someone who has confided in you is a breach of trust. The discussions in a secret meeting must be regarded as trust except in the case of murder, adultery and taking another's property unlawfully. Allah loves the truthful ones. Always speak the truth. Be honest at home , at play, at school and under all conditions.
Truthfulness leads to good conduct.
Allah does not guide the liar. Lying is a sign of the hypocrite. Be true in your intention, that is, be sincere. A sincere person does everything only to please Allah. A person was once left behind on the road.
