The Prophet said, "Allah said, 'I will be an opponent to three types of people on the Day of Resurrection: -1. One who makes a covenant in My Name, but proves treacherous; -2. One who sells a free person and eats his price; and -3. One who employs a laborer and takes full work from him but does not pay him for his lab our.' "

Allah's Apostle said, "There will be three types of people whom Allah will neither speak to them on the Day of Resurrection nor will purify them from sins, and they will have a painful punishment: They are, (1) a man possessed superfluous water (more than he needs) on a way and he withholds it from the travelers. (2) a man who gives a pledge of allegiance to an Imam (ruler) and gives it only for worldly benefits, if the Imam gives him what he wants, he abides by his pledge, otherwise he does not fulfill his pledge; (3) and a man who sells something to another man after the `Asr prayer and swears by Allah (a false oath) that he has been offered so much for it whereupon the buyer believes him and buys it although in fact, the seller has not been offered such a price." (See Hadith No. 838, Vol. 3)

The Prophet said, "There are three types of people whom Allah will neither talk to, nor look at, on the Day of Resurrection. (They are): -1. A man who takes an oath falsely that he has been offered for his goods so much more than what he is given, -2. a man who takes a false oath after the `Asr prayer in order to grab a Muslim's property, and -3. a man who withholds his superfluous water. Allah will say to him, "Today I will withhold My Grace from you as you withheld the superfluity of what you had not created."

Umar bin al-Khattab narrated that the Prophet (ﷺ) said... a similar report, in which he said: crisp or fresh.

The Prophet said, "(There are) three (types of persons to whom) Allah will neither speak to them on the Day of Resurrections, nor look at them (They are):--(1) a man who takes a false oath that he has been offered for a commodity a price greater than what he has actually been offered; (2) and a man who takes a false oath after the `Asr (prayer) in order to grab the property of a Muslim through it; (3) and a man who forbids others to use the remaining superfluous water. To such a man Allah will say on the Day of Resurrection, 'Today I withhold My Blessings from you as you withheld the superfluous part of that (water) which your hands did not create.' "

(The clerk of Al-Mughira) Muawiya wrote to Al-Mughira 'Write to me what you have heard from Allah's Apostle.' So he (Al-Mughira) wrote to him: Allah's Prophet used to say at the end of each prayer: "La ilaha illalla-h wahdahu la sharika lahu, lahul Mulku, wa lahul Hamdu wa hula ala kulli shai'in qadir. 'Allahumma la mani' a lima a'taita, wala mu'tiya lima mana'ta, wala yanfa'u dhuljadd minkal-jadd." He also wrote to him that the Prophet used to forbid (1) Qil and Qal (idle useless talk or that you talk too much about others), (2) Asking too many questions (in disputed Religious matters); (3) And wasting one's wealth by extravagance; (4) and to be undutiful to one's mother (5) and to bury the daughters alive (6) and to prevent your favors (benevolence to others (i.e. not to pay the rights of others (7) And asking others for something (except when it is unavoidable).

The Prophet used to invoke Allah with the following invocation: 'Rabbi-ghfir-li Khati 'ati wa jahli wa israfi fi `Amri kullihi, wa ma anta a'lamu bihi minni. Allahumma ighfirli khatayaya wa 'amdi, wa jahli wa jiddi, wa kullu dhalika'indi. Allahumma ighrifli ma qaddamtu wa ma akhartu wa ma asrartu wa ma a'lantu. Anta-l-muqaddimu wa anta-l-mu'akh-khiru, wa anta 'ala kulli shai'in qadir.'
