O people! If you have knowledge of any of your brothers' firmness in religion and correctness of ways, then do not listen to rumors about him. Look! Sometimes an archer shoots an arrow, and by chance the arrow misses, and the matter shifts a little from here to there, and whatever is a wrong statement will itself become null and void. Allah is the Hearer of everything and the Knower of every thing. It should be known that between truth and falsehood there is only the distance of four fingers. When the Imam was asked about its meaning, he gathered his fingers and placed them between his ear and eye and said: Falsehood is that which you say 'I heard,' and truth is that which you say 'I saw.'
