Musannaf Ibn Abi Shaybah

Hazrat Abu Dharr narrates from the Noble Prophet Muhammad (peace and blessings be upon him and his family) that he (peace and blessings be upon him and his family) said: "There are three people with whom Allah, the Exalted, will not speak on the Day of Resurrection, nor will He look at them, nor will He purify them, and for them is a painful punishment: (first) the one who lets his garment hang below his ankles, (second) the one who reminds others of his favors, and (third) the one who sells his goods by swearing a false oath."
