It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever helps someone in a dispute unjustly remains under the displeasure of Allah until he desists from it." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that whoever helps a falsehood (an unjust cause) in order to overturn the truth by means of it has indeed left the protection and security of Allah and of His Messenger (peace and blessings be upon him). This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "There is no burden of his parents' sin upon a child born of zina (a child born out of fornication)," (as the Qur'an says): "And no bearer of burdens will bear the burden of another." [Surah al-An'am: 164] This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it. However, the opposite (of this meaning) is also established through two sahih chains of narration.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) was asked about the child of zina (a child born of fornication), and he (peace and blessings be upon him) said: "He is the worst of the three." And the wording of the second chain is as follows:

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: "The child of zina is the worst of the three."

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that he said: The Aws and the Khazraj (the two tribes of the Ansar) boasted to one another, and the Aws said: Among us is the one whose testimony alone was deemed equal to the testimony of two men, namely Khuzaymah bin Thabit (may Allah be pleased with him). 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 Abdullah bin Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) turned the oath back onto the one seeking the right (the claimant). This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) 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: "Reconciliation between Muslims is permissible." A supporting report (shahid) for this hadith is the hadith of Sayyiduna Amr bin Awf (may Allah be pleased with him), and through it this (meaning) is known:

Kathir bin Abdullah narrates from his father, from his grandfather Sayyiduna Amr bin Awf (may Allah be pleased with him), who said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Reconciliation between Muslims is permissible, except a reconciliation that makes something lawful unlawful or makes something unlawful lawful; and Muslims are bound by their (agreed) conditions, except a condition that makes something lawful unlawful."

The son of Sayyiduna Ka'b bin Malik (may Allah be pleased with him) narrates from his father that the Messenger of Allah (peace and blessings be upon him) placed a restriction on the property of Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) (because of debt), and sold it to pay off the debt that he owed. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
