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."

Narrated Al-Ash'ath ibn Qays:

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.

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

Abu Dawud said: Ibrahim al-Sa'igh, the narrator of this tradition , was a pious man. Abu Muslim killed him at 'Aranda. When he raised a hammed and heard the call to prayer, he gave it up.

Abu Dawud said: This tradition has been transmitted by Dawud b. Abi al-Furat from Ibrahim al-Sa'igh as a statement of 'Aishah (not attributed to the Prophet). Similarly, it has been transmitted by al-Zuhri, 'Abd al-Malik b. Abi Sulaiman and Malik b. Mughul. All of them transmitted it from 'Ata on the authority of 'Aishah on her own statement.

The Messenger of Allah (ﷺ) as saying: Your oath should be about something regarding which your companion will believe you.

Musaddad said: 'Abd Allah b. Abi Salih narrated to me.

Abu Dawud said: Both of them refer to the same person: 'Abbad b. Abu Salih and 'Abd Allah b. Abi Salih.

Narrated Suwayd ibn Hanzalah:

We went out intending (to visit) the Messenger of Allah (ﷺ) and Wa'il ibn Hujr was with us. His enemy caught him. The people desisted from swearing an oath, but I took an oath that he was my brother. So he left him. We then came to the Messenger of Allah (ﷺ), and I informed him that the people desisted from taking the oath, but I swore that he was my brother. He said: You spoke the truth: A Muslim is a brother of a Muslim.

Sa'id ibn al-Musayyab said: There were two brothers among the Ansar who shared an inheritance. When one of them asked the other for the portion due to him, he replied: If you ask me again for the portion due to you, all my property will be devoted to the decoration of the Ka'bah.

Umar said to him: The Ka'bah does not need your property. Make atonement for your oath and speak to your brother. I heard the Messenger of Allah (ﷺ) say: An oath or vow to disobey the Lord, or to break ties of relationship or about something over which one has no control is not binding on you.

Narrated Abdullah ibn Amr ibn al-'As:

The Messenger of Allah (ﷺ) said: A vow is binding in those things by which the pleasure of Allah is sought, and an oath to break ties of relationship is not binding.

Narrated Abdullah ibn Amr ibn al-'As:

The Messenger of Allah (ﷺ) said: An oath or a vow about something over which a human being has no control, and to disobey Allah, and to break ties of relationship is not binding. If anyone takes an oath and then considers something else better than it, he should give it up, and do what is better, for leaving it is its atonement.

Abu Dawud said: All sound traditions from the Prophet (ﷺ) say: "He should make atonement for his oath," except those versions which are not reliable.

Abu Dawud said: I said to Ahmad: Yahya b. Sa'id (al-Qattan) has transmitted this tradition from Yahya b. 'Ubaid Allah. He (Ahmad b. Hanbal) said: But he gave it up after that, and he was competent for doing it. Ahmad said: His (Yahya b. 'Ubaid Allah's) tradition are munkar (rejected) and his father is not known.

Narrated Abdullah ibn Abbas:

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.

A similar tradition has been transmitted by 'Abd al-Rahman b. Samurah through a different chain if narrators. This version has: "Make atonement for your oath and then do the thing that is better."

Abu Dawud said: The version of this tradition transmitted by Abu Musa al-Ash'ari, 'Adi b. Hatim and Abu Hurairah are variant. Some of them indicate breaking the oath before making atonement, and other making atonement before breaking the oath.

Narrated Safiyyah bint Huyayy:

Ibn Harmalah said: Umm Habib gave us a sa' and told us narration from the nephew of Safiyyah on the authority of Safiyyah that it was the sa' of the Prophet (ﷺ).

Anas ibn Ayyad said: I tested it and found its capacity two and half mudd according to the mudd of Hisham.

When Khalid al-Qasri was made ruler (of Hijaz and Kufah), he doubled the measure of sa'. The sa' then measured sixteen rotls.

Abu Dawud said: Muhammad b. Muhammad b. Khattab was slain by Negroes in confinement. He said while signing with his hand: "in this way". Abu Dawud extended his hand and turned his palms towards earth and said: I saw him in the dream and asked him: How did Allah deal with you ? He replied: He admitted to Paradise. I said: Your detention did not harm you.

Narrated Ash-Sharid ibn Suwayd ath-Thaqafi:

Sharid's mother left a will to emancipate a believing slave on her behalf. So he came to the Prophet (ﷺ) and said: Messenger of Allah, my mother left a will that I should emancipate a believing slave for her, and I have a black Nubian slave-girl. He mentioned a tradition about the test of the girl.

Abu Dawud said: Khalid b. 'Abd Allah narrated this tradition direct from the Prophet (ﷺ). He did not mention the name of al-Sharid.

Narrated Ikrimah ibn AbuJahl:

The Prophet (ﷺ) said: I swear by Allah, I shall fight against the Quraysh; I swear by Allah, I shall fight against the Quraysh; I swear by Allah, I shall fight against the Quraysh. He then said: "If Allah wills."

Abu Dawud said: A number of persons have narrated this tradition from Sharik, from Simak, from 'Ikrimah, from Ibn 'Abbas who reported from the Prophet (ﷺ): "But he did not fight against them."

The Prophet (ﷺ) as saying: I swear by Allah, I shall fight against the Quraish. The then said: If Allah wills. He again said: I swear by Allah, I shall fight against the Quraish if Allah wills. He again said: I swear by Allah, I shall fight against the Quraish. He then kept silence. Then he said: If Allah wills.

Abu Dawud said: Al-Walid b. Muslim said on the authority of Sharik: He then said: But he did not fight against them.

The Messenger of Allah (ﷺ) forbade to make a vow. He said: It has not effect against fate, it is only from the miserly that it is means by which something is extracted.

Musaddad said: The Messenger of Allah (ﷺ) said: A vow does not avert anything (i.e. has no effect against fate).

Narrated Aisha, Ummul Mu'minin:

The Prophet (ﷺ) as saying: No vow must be taken to do an act of disobedience, and the atonement for it is the same as for an oath.

The tradition mentioned above has also been transmitted by al-Zuhri through a different chain of narrators to the same effect.

Abu Dawud said: I heard Ahmad b. Shabbuyah say: Ibn al-Mubarak said about this tradition that Abu Salamah had transmitted it. This indicates that al-Zuhri did not hear it from Abu Salamah. Ahmad b. Muhammad said: This is verified by what Ayyub b. Sulaiman narrated to us.

Abu Dawud said: I heard Ahmad b. Hanbal say: I have corrupted this tradition for us. He was asked: Do you think that it is correct that this tradition has been corrupted? Has any person other than Ibn Abi Uwais transmitted it ? He replied: Ayyub was similar to him in respect of reliability, and Ayyub transmitted it.
