Abu Bakr ibn Abi Shaybah and Abu Kurayb narrated to us—and this is the hadith of Abu Bakr—saying: Abu Mu'awiyah narrated to us, from al-A'mash, from Abu Salih, from Abu Hurayrah, who said: The Messenger of Allah, peace and blessings be upon him, said: "Three persons Allah will not speak to on the Day of Resurrection, nor look at them, nor purify them, and they will have a painful punishment: a man who has surplus water in the desert and withholds it from the wayfarer; and a man who sells goods to another man after the afternoon prayer, swearing by Allah that he paid such-and-such for it, and the buyer believes him, while it was not so; and a man who pledges allegiance to a ruler, pledging only for worldly gain—if he gives him something of it, he fulfills, and if he does not give him something of it, he does not fulfill."
