Truth is one of the Islamic moral values, either in the relationship of man with his God, or with himself, or with people. To live the idea of truth is not to falsify his mind with lies which he reads and hears. Truth is in words, such as not to speak against the truth, and falsify the reality for people.And truth is in actions, such as his attitude should be inconsistent with his principles, faith, and doctrine. Hence, his attitude should not differ from his faithful commitments. Thus truth is represented by his relationship to reality, and the commitment with right and being away from falsehood.
