Sahih Muslim Book 1, Hadith Number 195.

Chapter : Serious prohibition of letting down the lower garment: of laying obligation of selling goods by false oaths, and description of those three (persons) with whom Allah would not speak on the Day of Resurrection nor would He see towards them nor would absolve them, and for them is a painful chastisement.

It is narrated on the authority of Abu Huraira that the Messenger of Allah (may peace be upon him) observed: Three (are the persons) with whom Allah would neither speak, nor would He absolve them on the Day of Resurrection. Abu Mu’awiya added: He would not look at them and there is grievous torment for them: the aged adulterer, the liar king and the proud destitute.
