It was narrated from Abu Dharr that the Prophet said:
There are three to whom Allah will not speak on the Day of Resurrection, or look at them, or sanctify them, and theirs will be a painful torment. The Messenger of Allah repeated and Abu Dharr said: May they be lost and doomed. He said: The one who lets his garment hang beneath his ankles, a vendor who tries to sell his product by means of false oaths, and the one who reminds people of what he has given them.
