We said, "Yes, O ALLAH's ApostleSal-Allahu Alaihi Wasallam " He said, "To join partners in worship with ALLAH: to be undutiful to one's parents."

Sahih Bukhari, Vol 8, Book 73, No. 7: 

✦ Abdullah ibn masood Radhi allahu anhu reported the Messenger of Allah (May peace be upon him) as saying : 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. And adhere to truth, for truth leads to good deeds, and good deeds lead to paradise. If a man continues to speak the truth and makes truth his object, he will be recorded in Allah’s presence as eminently truthful.
