Musnad Abu Ya'la al-Mawsili 152:70

Abu Khaythama narrated to us, Jarir narrated to us, from Mansur, from Abu Wa'il, from Abdullah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, truthfulness guides to righteousness, and righteousness guides to Paradise. A man continues to be truthful until he is recorded as a truthful person (siddiq). And indeed, lying guides to wickedness, and wickedness guides to the Fire. A man continues to lie until he is recorded with Allah as a liar."
