Sahih Muslim, Chapter: Faith (Kitab Al Iman)

It is narrated o the authority of Abu Dharr that the Messenger of Allah (may ace he upon him) observed: Three are the (persons) with whom Allah would neither speak on the Day of Resurrection, nor would look at them nor would absolve the and there is a painful chastisement for them. The Messenger of Allah (may peace be upon him) repeated it three times. Abu Dharr remarked: They failed and they lost; who are these persons, Messenger of Allah? Upon this he (the Holy) Prophet) observed: They are: the dragger of lower garment, the recounter of obligation the seller of goods by false oath.
