A bedouin came to the Prophet and said, "O Allah's Apostle! What are the biggest sins?: The Prophet said, "To join others in worship with Allah." The bedouin said, "What is next?" The Prophet said, "To be undutiful to one's parents." The bedouin said "What is next?" The Prophet said "To take an oath 'Al-Ghamus." The bedouin said, "What is an oath 'Al-Ghamus'?" The Prophet said, "The false oath through which one deprives a Muslim of his property (unjustly).

Allah's Apostle said, "If somebody is ordered (by the ruler or the judge) to take an oath, and he takes a false oath in order to grab the property of a Muslim, then he will incur Allah's Wrath when he will meet Him." And Allah revealed in its confirmation: 'Verily! Those who purchase a small gain at the cost of Allah's covenants and their own oaths.' (3.77) (The sub-narrator added:) Al-Ash'ath bin Qais entered, saying, "What did Abu `Abdur-Rahman narrate to you?" They said, "So-and-so," Al-Ash'ath said, "This verse was revealed in my connection. I had a well on the land of my cousin (and we had a dispute about it). I reported him to Allah 's Apostle who said (to me). "You should give evidence (i.e. witness) otherwise the oath of your opponent will render your claim invalid." I said, "Then he (my opponent) will take the oath, O Allah's Apostle." Allah's Apostle said, "Whoever is ordered (by the ruler or the judge) to give an oath, and he takes a false oath in order to grab the property of a Muslim, then he will incur Allah's Wrath when he meets Him on the Day of Resurrection."

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.' "

`Abdullah bin Masud said, "Allah's Apostle said, 'Whoever takes an oath when asked to do so, in which he may deprive a Muslim of his property unlawfully, will meet Allah Who will be angry with him.' So Allah revealed in confirmation of this statement:--"Verily! Those who Purchase a small gain at the cost of Allah's Covenant and oaths, they shall have no portion in the Hereafter..." (3.77) Then entered Al-Ash'ath bin Qais and said, "What is Abu `Abdur-Rahman narrating to you?" We replied, 'So-and-so." Al-Ash'ath said, "This Verse was revealed in my connection. I had a well in the land of my cousin (and he denied my, possessing it). On that the Prophet said to me, 'Either you bring forward a proof or he (i.e. your cousin) takes an oath (to confirm his claim)' I said, 'I am sure he would take a (false) oath, O Allah's Apostle.' He said, 'If somebody takes an oath when asked to do so through which he may deprive a Muslim of his property (unlawfully) and he is a liar in his oath, he will meet Allah Who will be angry with him.' "

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."

I asked Ibn `Umar, "(What is the verdict if) a man accuses his wife of illegal sexual intercourse?" Ibn `Umar said, "The Prophet separated (by divorce) the couple of Bani Al-Ajlan, and said, (to them), 'Allah knows that one of you two is a liar; so will one of you repent?' But both of them refused. He again said, 'Allah knows that one of you two is a liar; so will one of you repent?' But both of them refused. So he separated them by divorce." (Aiyub, a sub-narrator said: `Amr bin Dinar said to me, "There is something else in this Hadith which you have not mentioned. It goes thus: The man said, 'What about my money (i.e. the Mahr that I have given to my wife)?' It was said, 'You have no right to restore any money, for if you have spoken the truth (as regards the accusation), you have also consummated your marriage with her; and if you have told a lie, you are less rightful to have your money back.' ")

The Prophet said, "Whoever takes the property of a Muslim by taking a false oath, will meet Allah Who will be angry with him." Then the Prophet recited the Verse:-- 'Verily those who purchase a small gain at the cost of Allah's Covenant and their oaths, they shall have no portion in the Hereafter, neither will Allah speak to them, nor look at them.' (3.77)

The Prophet said, "Whoever swears falsely in order to grab the property of a Muslim (or of his brother), Allah will be angry with him when he meets Him." Allah then revealed in confirmation of the above statement:--'Verily those who purchase a small gain at the cost of Allah's Covenant and their own oaths.' (3.77) Al-Ash'ath said, "This Verse was revealed regarding me and a companion of mine when we had a dispute about a well."

I asked Ibn `Umar about those who were involved in a case of Lien. He said, "The Prophet said to those who were involved in a case of Lien, 'Your accounts are with Allah. One of you two is a liar, and you (the husband) have no right over her (she is divorced)." The man said, 'What about my property (Mahr) ?' The Prophet said, 'You have no right to get back your property. If you have told the truth about her then your property was for the consummation of your marriage with her; and if you told a lie about her, then you are less rightful to get your property back.' " Sufyan, a sub-narrator said: I learned the Hadith from `Amr. Narrated Aiyub: I heard Sa`id bin Jubair saying, "I asked Ibn `Umar, 'If a man (accuses his wife for an illegal sexual intercourse and) carries out the process of Lian (what will happen)?' Ibn `Umar set two of his fingers apart. (Sufyan set his index finger and middle finger apart.) Ibn `Umar said, 'The Prophet separated the couple of Bani Al-Ajlan by divorce and said thrice, "Allah knows that one of you two is a liar; so will one of you repent (to Allah)?' "

I said to Ibn `Umar, "If a man accuses his wife of illegal sexual intercourse (what is the judgment)?" He said, "Allah's Prophet separated the couple of Bani 'Ajlan (when the husband accused his wife for an illegal sexual intercourse). The Prophet said, 'Allah knows that one of you two IS a liar; so will one of you repent?' But they refused. He then again said, 'Allah knows that one of you two is a liar; so will one of you repent?' But they refused, whereupon he separated them by divorce." Aiyub (a subnarrator) said: `Amr bin Dinar said to me, "In the narration there is something which I do not see you mentioning, i.e. the husband said, "What about my money (Mahr)?' The Prophet said, "You are not entitled to take back money, for if you told the truth you have already entered upon her (and consummated your marriage with her) and if you are a liar then you are less entitled to take it back.

The Prophet said, "Whoever takes a false oath to deprive somebody of his property will meet Allah while He will be angry with him." Allah revealed: 'Verily those who purchase a little gain at the cost of Allah's covenant, and their oaths.' ........(3.77) Al-Ashath came (to the place where `Abdullah was narrating) and said, "What has Abu `Abdur- Rahman (i.e. `Abdullah) been telling you? This verse was revealed concerning me. I had a well in the land of a cousin of mine. The Prophet asked me to bring witnesses (to confirm my claim). I said, 'I don't have witnesses.' He said, 'Let the defendant take an oath then.' I said, 'O Allah's Apostle! He will take a (false) oath immediately.' Then the Prophet mentioned the above narration and Allah revealed the verse to confirm what he had said." (See Hadith No. 692)

The Prophet said to those who were involved in a case of Lian, "Your accounts are with Allah. One of you two is a liar. You (husband) have right on her (wife)." The husband said, "My money, O Allah's Apostle!" The Prophet said, "You are not entitled to take back any money. If you have told the truth, the Mahr that you paid, was for having sexual relations with her lawfully; and if you are a liar, then you are less entitled to get it back."

I heard the Messenger of Allah (saws) say: It is great treachery that you should tell your brother something and have him believe you when you are lying.

I heard Allah's Apostle saying, "All of you are guardians and responsible for your charges: the Ruler (i.e. Imam) is a guardian and responsible for his subjects; and a man is a guardian of his family and is responsible for his charges; and a lady is a guardian in the house of her husband and is responsible for her charge; and a servant is a guardian of the property of his master and is responsible for his charge." I think he also said, "And a man is a guardian of the property of his father."

The Prophet said, "If somebody on the demand of a judge takes an oath to grab (a Muslim's) property and he is liar in it, he will meet Allah Who will be angry with him". So Allah revealed,:-- 'Verily! those who purchase a small gain at the cost of Allah's Covenant and their oaths..' (3.77) 'Al- Ashath came while `Abdullah was narrating (this) to the people. Al-Ashath said, "This verse was revealed regarding me and another man with whom I had a quarrel about a well. The Prophet said (to me), "Do you have any evidence?' I replied, 'No.' He said, 'Let your opponent take an oath.' I said: I am sure he would take a (false) oath." Thereupon it was revealed: 'Verily! those who purchase a small gain at the cost of Allah's Covenant....' (3.77) (See Hadith No. 72, Vol 6).
