It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: There are three unfortunate people with whom Allah Almighty will not speak on the Day of Resurrection: First, the person who has surplus water but does not give it to a traveler; second, the person who swears a false oath to sell his goods; third, the person who pledges allegiance to the Imam, and if the Imam gives him something, he fulfills the pledge, but if he does not give him anything, he does not fulfill it.
