We should speak truth it has many benefits. We can develop the patmosphere of piece by telling truth. Telling lie is root of sins.
@AleemKhan I assume you mean atmosphere of peace. The Prophet (SAW) also said "Speak the truth even if it is against yourself" .This underscores the importance of truthfulness.

May Allah make it easy for us to be among the truthful ones.
