📖 Abdullah Ibn Mas’ud RadhiAllahu 'anhu narrated:
Allah's noble Messenger Muhammad SallAllahu 'alaihi wa sallam said, "You
must be truthful. Verily, truthfulness leads to righteousness and righteousness
leads to Paradise. A man continues to be truthful and encourages honesty until
he is recorded with Allah as a truthful person. And beware of falsehood.
Verily, falsehood leads to wickedness and wickedness leads to the Hellfire. A
man continues to tell lies and encourages falsehood until he is recorded with
Allah as a liar."
