Sa'id bin al-Musayyib narrates that there was a matter of dividing an inheritance between two brothers of the Ansar. One of them asked the other (for the division), and he swore: If you ask me again, I will never speak to you, and all my wealth is dedicated to the Ka'bah. Sayyiduna Umar (may Allah be pleased with him) said: The Ka'bah has no need of your wealth; expiate your oath and speak to your brother, for I heard the Messenger of Allah (peace and blessings be upon him) say: "No oath or vow is binding upon you in disobedience to Allah, in severing ties of kinship, or in what you do not own." This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.

Tamim al-Ta'i narrates that a man came to Sayyiduna Adi bin Hatim (may Allah be pleased with him) and said: I have married a woman, so give me (some help). He offered to write him an order for a coat of mail and a helmet, but the man was displeased with it, whereupon Adi (may Allah be pleased with him) swore that he would not give them to him. The man said: I was hoping you would give me a servant. He said: By Allah, these two are dearer to me than two servants. The man said: Then write me an order for them. Adi (may Allah be pleased with him) said: Had I not heard the Messenger of Allah (peace and blessings be upon him) say, "If one of you swears an oath and then sees something better than it, let him do what is better," I would not have given them to you; then he wrote the order for them for him. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it with this wording.

It is narrated from Sayyiduna Abu al-Darda (may Allah be pleased with him) that Allah granted His Messenger some camels as spoils (fay'), and the Prophet (peace and blessings be upon him) distributed them. Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) said: O Messenger of Allah, give me a share. He said: "No." He asked him three times, and the Messenger of Allah (peace and blessings be upon him) said: "I will not do it." Then four camels with white humps remained, and he said: "O Abu Musa, take them." He said: O Messenger of Allah, I feel shy; I asked you and you refused me and swore, and I feared that the Messenger of Allah (peace and blessings be upon him) might have become mistaken. The Messenger of Allah (peace and blessings be upon him) said: "When I swear an oath and then see that something other than it is better, I expiate my oath and do what is better." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

The Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), narrates that when the Messenger of Allah (peace and blessings be upon him) swore an oath about something, he would not break it, until Allah Almighty revealed the ruling on the expiation of oaths. Then he (peace and blessings be upon him) said: "Now, when I swear an oath about something and see good in something else, I give the expiation for my oath and do that in which there is good." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever stubbornly persists in an oath (that causes harm) sworn concerning his family, that is a cause of greater sin for him (than breaking the oath)." This hadith is sahih (authentic) on the condition of Imam Bukhari.
