Riyad us Saliheen: Hadith 1851

The Messenger of Allah (ﷺ) said, "There are three (types of) people whom Allah will neither speak to on the Day of Resurrection nor will He purify them (i.e., from their sins), nor will look upon them; and they will have a painful chastisement. These are: An old man who commits fornication; a king who is a great liar and a poor man who is proud."
