The Messenger of Allah ﷺ said, "There are three whom Allah will not speak to on the Day of Resurrection, nor will He look at them, nor will He purify them, and for them is a painful punishment. A man who has surplus water by the roadside and withholds it from the wayfarer. A man who pledges allegiance to a leader only for worldly gain, so that if the leader gives him what he wants he honors the pledge, but if he does not give it, he breaks it. And a man who haggles with another over goods after the afternoon prayer, swearing by Allah that he was offered such and such for them, and the other man believes him."
أخبرنا إسحق بن إبراهيم قال أنبأنا جرير عن الأعمش عن أبي صالح
عن رسول الله ﷺ قال ثلاثة لا يكلمهم الله عز وجل ولا ينظر إليهم يوم القيامة ولا يزكيهم ولهم عذاب أليم رجل على فضل ماء بالطريق يمنع ابن السبيل منه ورجل بايع إماما لدنيا إن أعطاه ما يريد وفى له وإن لم يعطه لم يف له ورجل ساوم رجلا على سلعة بعد العصر فحلف له بالله لقد أعطي بها كذا وكذا فصدقه الآخر
