Imam al-Hakim says: Abu Bakr bin Ishaq informed us, from Abdullah bin Ahmad bin Hanbal, from his father (Imam Ahmad bin Hanbal), from Imam al-Shafi'i (may Allah have mercy on him), who narrated this report; and at its end Imam Ahmad bin Hanbal (may Allah have mercy on him) said: I was informed via Hisham bin Yusuf, from Ibn Jurayj, who narrated from Isma'il bin Umayyah, who narrated from Abd al-Malik bin Ubayd. Imam Ahmad bin Hanbal says that Hajjaj al-A'war gave this narrator's name as "Abd al-Malik bin Ubaydah".

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) bought a load of fallen tree leaves from a Bedouin (the narrator said: I think he said: from Banu Amir bin Sa'sa'ah). When the sale became binding, he (peace and blessings be upon him) said to him: "(Even now, if you wish, you may) choose (to cancel the sale)." The Bedouin said: By Allah! I have never seen as fine a trader as you; may Allah lengthen your life, which tribe are you from? He (peace and blessings be upon him) said: "I am from Quraysh."

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) bought a load of tree leaves from a Bedouin. When the deal was concluded, he (peace and blessings be upon him) said: "You have the choice (to cancel the sale)." The Bedouin said: May Allah lengthen your life, you are a most excellent trader. This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The one who takes usury (riba) and the one who gives it are equal (in sin)." 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 Ali bin Abi Talib (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "A dinar for a dinar and a dirham for a dirham (must be equal), with no excess between them. Whoever needs silver should exchange gold for it on the spot, and whoever needs gold should exchange silver for it on the spot; and this exchange must be hand to hand and on the spot." This hadith is gharib (singular) and sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it with this wording.

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: "Muslims are bound by their (agreed) conditions, and making peace (settlement) between Muslims is permissible." Its narrators are from Madinah, and the two Shaykhs (Bukhari and Muslim) did not record it. It is one of the foundational principles of fiqh, and supporting narrations (shawahid) for it are also reported from Sayyidah Aishah and Sayyiduna Anas (may Allah be pleased with them both).

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Muslims are bound by their (agreed) conditions, as long as they are in accordance with the truth."

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Muslims abide by their conditions, as long as those conditions are in accordance with the truth."

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Every good deed is charity. Whatever a man spends on himself and his family is recorded for him as charity, and whatever a person uses to protect his honour is also recorded for him as charity. Whatever a believer spends, Allah Almighty will give its replacement and is its guarantor, except what is spent on constructing a building or in sin." The narrator says: I asked Muhammad bin al-Munkadir: "How does a man protect his honour?" He replied: "What he gives to a poet or to a foul-tongued person (to silence his tongue, so that his honour remains safe)." This hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever among you is able to protect his religion and his honour with his wealth should certainly do so."
