Sahih Muslim Book 32, Hadith Number 6307.

Chapter : The evil of a lie and the goodness of truth and its merit.

‘Abdullah reported Allah’s Messenger (may peace be upon him) as saying: Truth leads one to Paradise and virtue leads one to Paradise and the person tells the truth until he is recorded as truthful, and lie leads to obscenity and obscenity leads to Hell, and the person tells a lie until he is recorded as a liar.
