It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that during the time of the Messenger of Allah (peace and blessings be upon him) there was a man who used to buy and sell, and there was some weakness in his judgement (that is, in his intellect or power of decision). His family came to the Prophet (peace and blessings be upon him) and said: O Prophet of Allah, place a restriction (on trading) on so-and-so, for he makes deals and there is weakness in his understanding. So the Prophet (peace and blessings be upon him) called him and forbade him from buying and selling. He said: O Prophet of Allah, I cannot do without trading. So he (peace and blessings be upon him) said: "If you are not going to give up trading, then say (when making a deal): 'Ha wa la khilabah' (Here it is, and let there be no deception)." 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 Abd al-Rahman bin al-Baylamani that he said: In Alexandria I saw an old man who was called "Surraq" (thief). I went to him and asked him about it, and he told me: the Messenger of Allah (peace and blessings be upon him) gave me this name, and I will never give it up. I asked: Why did he give you this name? He said: A man from the desert came with two camels, and I bought them from him. Then I went into my house and left by the back way; I sold the camels on and met my need with them, and I stayed away until I thought that the Bedouin must have left by now. But he was still staying there. He seized me and took me to the Messenger of Allah (peace and blessings be upon him) and told him the whole story. He (peace and blessings be upon him) said: "What made you do what you did?" I said: O Messenger of Allah, I met my need with them. He (peace and blessings be upon him) said: "Pay him his due." I said: I have nothing with me right now. He (peace and blessings be upon him) said: "You are Surraq. O Bedouin, go and sell him (as a slave) until you receive your full due." He said: So people began bidding to the Bedouin for me, and he would turn to them and say: What do you want? They would say: We want to ransom him from you. So the Bedouin said: By Allah, I am more deserving of this than all of you and more in need of Allah, the Mighty and Majestic (and His forgiveness). (O man,) go, I have set you free for the sake of Allah. This hadith is sahih (authentic) on the condition of Imam Bukhari, but the two Shaykhs (Bukhari and Muslim) did not record it.

Bahz bin Hakim narrates from his father, who narrates from his grandfather, that the Prophet (peace and blessings be upon him) imprisoned a man on the basis of an accusation. 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 Prophet (peace and blessings be upon him) imprisoned a man on the basis of an accusation for a day and a night, for thorough investigation and as a precaution.

Amr bin al-Sharid narrates from his father that the Messenger of Allah (peace and blessings be upon him) said: "Delay (in repaying a debt) by one who has the means makes lawful (action against) his honour and his punishment." 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 Abdullah bin Amr (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) cursed the one who gives a bribe and the one who takes a bribe. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it. A supporting report (shahid) for it is the well-known hadith of Sayyiduna Abu Hurayrah (may Allah be pleased with him) and the narration of Sayyiduna Thawban (may Allah be pleased with him). As for the hadith of Sayyiduna Abu Hurayrah (may Allah be pleased with him):

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) cursed the one who gives a bribe and the one who takes a bribe in matters of judicial ruling.

Sayyiduna Thawban (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him) that he said: "Cursed are the one who gives a bribe, the one who takes a bribe, and the ra'ish, that is, the one who runs about between the two (to arrange the deal)." I have mentioned Umar bin Abi Salamah and Layth bin Abi Sulaym as supporting reports (shawahid), not as primary narrations.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever is made ruler or judge over ten people, whether they like his judgement or dislike it, will be brought on the Day of Resurrection with his hand shackled to his neck. Then, if he judged according to what Allah revealed, did not take bribes in his judgement and did not act unjustly, Allah Almighty will release him on the Day of Resurrection, the day on which there will be no shackle except His shackle. But if he judged by other than what Allah revealed, took bribes in his judgement and showed partiality, his left hand will be bound to his right, then he will be thrown into Hell, and he will not reach its bottom for five hundred years." Sa'dan bin al-Walid al-Bajali of Kufah is a narrator with few hadith, and the two Shaykhs (Bukhari and Muslim) did not narrate from him.

It is narrated from Sahl bin Atiyyah that he said: I was with Bilal bin Abi Burdah at al-Taff when a man (al-Da'l) came and complained to him that the people of al-Taff do not pay zakah. Bilal sent a man to investigate what they were saying, and that man found that the lineage of this complainant was impugned. He came back and informed Bilal, whereupon Bilal said "Allahu Akbar" and said: My father narrated to me from Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever runs about (to harm) people or carries tales is not of legitimate birth, or there is some trace of that in him." This hadith, narrated from Bilal bin Abi Burdah, has several chains, of which this is the best.
