Mishkat al-Masabih

He reported God’s Messenger as saying, “There are three to whom God will not speak and at whom He will not look on the day of resurrection:a man who swears falsely about some merchandise that he has previously received a larger offer than he has now been given; a man who swears a false oath after the afternoon prayer to deprive thereby a Muslim of his property; and a man who withholds excess water. God will say, ‘Today I am withholding from you my grace*as you withheld excess water which was not produced by the efforts of your hands’." (Bukhari and Muslim.) *The word for grace (fadl) is the same as the word for excess.
