question #2 Sahih Muslim 106a, Book 1, Hadith 199 : Who are the individuals that will face severe consequences according to the teachings of the Prophet?

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 (ﷺ) 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.
