Imam Ali (AS) said:

When you hear the news/stories/reports, think about them with the wisdom that confirms their accuracy, not just with the wisdom of the storyteller and the newscaster, because there are many newscasters/storytellers, but the ones who observe the accuracy and the truth behind the news are few and far between [1].
