It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: On the Day of Resurrection, Allah Almighty will neither speak to three types of people, nor will He look at them with mercy, nor will He purify them; rather, there will be a painful punishment for them. 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, sells some merchandise and swears by Allah before the buyer that he bought the item for such and such a price, and the buyer believes him, while in reality he is not telling the truth.
