The Prophet (ﷺ) said: If anyone swears a false oath in confinement, he should make his seat in Hell on account of his (act).

The Prophet (ﷺ) said: One should not take a false oath at this pulpit of mine even on a green tooth-stick; otherwise he will make his abode in Hell, or Hell will be certain for him.

The Messenger of Allah (ﷺ) said: He who swears an oath in which he tells a lie to take the property of a Muslim by unfair means, will meet Allah while He is angry with him.

Al-Ash'ath said: I swear by Allah, he said this about me. There was some land between me and a Jew, but he denied it to me; so I presented him to the Prophet (ﷺ).

The Prophet (ﷺ) asked me: Have you any evidence? I replied: No. He said to the Jew: Take an oath. I said: Messenger of Allah, now he will take an oath and take my property. So Allah, the Exalted, revealed the verse, "As for those who sell the faith they owe to Allah and their own plighted word for a small price, they shall have no portion in the hereafter."

A man of Kindah and a man of Hadramawt brought their dispute to the Prophet (ﷺ) about a land in the Yemen. Al-Hadrami said: Messenger of Allah, the father of this (man) usurped my land and it is in his possession.

The Prophet asked: Have you any evidence?

Al-Hadrami replied: No, but I make him swear (that he should say) that he does not know that it is my land which his father usurped from me.

Al-Kindi became ready to take the oath.

The Messenger of Allah (ﷺ) said: If anyone usurps the property by taking an oath, he will meet Allah while his hand is mutilated.

Al-Kindi then said: It is his land.

On the Authority of his father: A man from Hadramawt and a man of Kindah came to the Messenger of Allah (ﷺ). Al-Hadrami said: Messenger of Allah, this (man) took away forcibly from me the land which belongs to my father. Al-Kindi said: It is my land in my possession, and I cultivate it, he has no right to it. The Prophet (ﷺ) then said to al-Hadrami: Have you any proof ? He said: No. He then said: So for you is his oath. He said: Messenger of Allah, he is liar, he does not care for which he is taking the oath. He does not refrain himself from anything. The Prophet (ﷺ) said: You will have nothing from him except that. He went to take an oath for him. When he turned his back, the Messenger of Allah (ﷺ) said: If he takes an oath on the property to take it away by unfair means, he will meet Allah while He is unmindful of him.

The Messenger of Allah (ﷺ) as saying: If anyone swears on oath is the course which he says: "By al-Lat" he should say: There is no god but Allah, and that if anyone says to his friend: Come and let me play for money with you, he should give something in charity (sadaqah).

Two men brought their dispute to the Prophet (ﷺ). The Prophet (ﷺ) asked the plaintiff to produce evidence, but he had no evidence. So he asked the defendant to swear. He swore by Allah "There is no god but He."

The Messenger of Allah (ﷺ) said: Yes, you have done it, but you have been forgiven for the sincerity of the statement: "There is no god but Allah."

Abu Dawud said: This tradition means that he did not command him to make atonement

The Prophet (ﷺ) said to me: 'Abd al-Rahman b. Samurah, when you swear an oath and consider something else to be better than it, do the thing that is beter and make atonement for your oath.

Abu Dawud said: I heard Ahmad (b. Hanbal) permitting to make atonement before breaking the oath.

The Messenger of Allah (ﷺ) saw a man that he was supported between his sons. He asked about him, and (the people) said: He has taken a vow to walk (on foot). Thereupon he said: Allah has no need that this man should punish himself, and he ordered him to ride.
