It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: There are three types of people with whom Allah will neither speak on the Day of Resurrection, nor will He look at them with mercy, nor will He purify them, and for them there will be a painful punishment. The first is the person who has surplus water in a desert area and refuses to give it to a traveler. The second is the person who pledges allegiance to a ruler, but his intention is only worldly gain; if he gets it, he remains loyal to the ruler, but if he does not get it, he does not fulfill his pledge of allegiance. The third is the person who, after the Asr prayer, swears a false oath and sells his merchandise.
