Syedna Abu Hurairah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: Allah Almighty will neither speak to three types of people, nor look at them, nor purify them, and for them there will be a painful punishment: The first is the person who takes possession of surplus water in a desert and prevents a traveler from it; the second is the person who pledges allegiance to a ruler only for worldly gain—if he is given worldly wealth, he fulfills the pledge, and if he is not given anything, he does not fulfill it; the third is the person who, after Asr prayer, sells his goods and swears that he bought the goods for such and such a price, so the buyer believes him because of his oath, while in reality his claim is false.
