Allâh's Messenger (ﷺ) said, "There are three types of people whom Allâh will neither look at them on the Day of Resurrection, nor will He purify them (from sins) and they shall have a painful torment. They are:1. A man possessed superfluous water, on a way and he withheld it from travellers. 2. A man who gave a Bai'a (pledge) to a ruler and he gave it only for worldly benefits. If the ruler gives him something he gets satisfied, and if the ruler withholds something from him, he gets dissatisfied. 3. And a man displayed his goods for sale after the ' prayer (and took a false oath by) saying, 'By Allâh, except Whom none has the right to be worshipped, I have been given so much for my goods, 'and somebody believes him (and buys them)." The Prophet (ﷺ) then recited:-" Verily ! Those who purchase a small gain at the cost of Allâh's Covenant and their oaths." (V.3:77) [3:547-O.B]
