Avoid falsehood, for falsehood leads to wickedness, and wickedness to hell; and if a man continues to speak falsehood and makes falsehood his object, he will be recorded in Allah's presence as a great liar.

If a man continues to speak the truth and makes truth his object, he will be recorded in Allah's presence as eminently truthful.
