He heard Allah's Messenger (ﷺ) say. "The testimony of a bedouin against a city dweller is not permissible."[Reported by Abu Dawud and Ibn Majah].

He addressed the people and said, "People were sometimes judged by the revealing of a Divine Revelation during the lifetime of Allah's Messenger (ﷺ), but now the Divine Revelation has been discontinued [i.e. there is no longer any new revelation coming]. Now we judge you by the deeds you practice publicly."[Reported by al-Bukhari].

The Prophet (ﷺ) considered Shahadah az-Zur (giving false testimony) among the most serious of major sins.[al-Bukhari and Muslim reported it in a long Hadith].

The Prophet (ﷺ) said to a man, "Do you see the sun?" He replied, "Yes." He said, "Give witness in a similar case [which is as clear as the sun], or leave it."[Ibn 'Adi reported it with a Da'if (weak) chain or narrators, and al-Hakim graded it Sahih (authentic), but he was mistaken].

Allah's Messenger (ﷺ) ruled on the basis of an oath and a single witness.[Muslim, Abu Dawud and an-Nasa'i reported it, the latter said that it has a Jayyid (good) chain or narrators].

Something similar to the aforesaid Hadith.[Abu Dawud and at-Tirmidhi reported it. Ibn Hibban graded it Sahih (authentic)].

The Prophet (ﷺ) said: "If people were given whatever they claimed (in disputes), some people would claim the lives and wealth of others; but the oath (of denial) must be taken by the defendant."[Agreed upon]. al-Baihaqi has reported with a Sahih (authentic) chain of narrators: "But the proof (Bayyinah) lies on the one who is making the claim, and the other (Yamin) must be taken by the one who rejects the claim."

The Prophet (ﷺ) suggested to some people that they should take an oath (Yamin) and when they hastened to do so he ordered that lots should be cast among them concerning the oath, as to which of them should take it.[Reported by al-Bukhari].

Allah's Messenger (ﷺ) said. "If anyone seized - by his oath - what rightly belongs to a Muslim, Allah has made the Hell-fire compulsory for him and forbidden for him the Paradise." A man asked, "O Allah's Messenger, even if it were something insignificant?" He replied, "Even if it were a stick from an Arak tree."[Reported by Muslim].

Allah's Messenger (ﷺ) said: "If anyone swears a firm oath - knowingly, intentionally, taking by it property belonging to a Muslim, Allah will be angry with him when he meets Him (on the Day of Resurrection)."[Agreed upon].

Two men had a disputer over an animal, and neither of them had a proof. So Allah's Messenger (ﷺ) gave a ruling that it be divided in halves between them.[Reported by Ahmad, Abu Dawud and an-Nasa'i, and the wording is his (an-Nasa'i) who said that it's chain of narrators is Jayyid (good)].

The Prophet (ﷺ) said: "If anyone swears a false oath on this Minbar of mine, he will have prepared his seat in the Hell-Fire."[Reported by Ahmad, Abu Dawud and an-Nasa'i. Ibn Hibban graded it Sahih (authentic)].

Allah's Messenger (ﷺ) said: "There are three to whom Allah will not speak to on the Day of Resurrection, not will He look at them, nor will He purify them, and they will have a painful punishment. (1) A man at a place with excess water in the desert and who withholds it from the travelers. (2) A man who sold a commodity to another person in the afternoon (or after the 'Asr prayer) and swore to him by Allah that he had bought it at such and such price and he (the buyer) believed him yet that was not the case. (3) And a man who pledged allegiance to an Imam only for the sake of the world (material gains). Hence, if the Imam bestowed on him something out of that (i.e. worldly riches) he stood by his pledge of allegiance, and if he did not give him, he did not fulfill the pledge of allegiance."[Agreed upon].

Two men disputed about a she-camel. Then, each of them said: this she-camel was born at my place, and each of them brought a proof (that it was his animal). Allah's Messenger (ﷺ) then ruled that it be taken by the one who had it in his possession.

The Prophet (ﷺ) re-directed al-Yamin (the oath to be sword by the defendant) to the one making the claim to some right.[ad-Daraqutni reported the two aforesaid Ahadith, and there is weakness in their chain of narrators].

One day the Prophet (ﷺ) came to me overjoyed, his face shining (from happiness) and said, "Did you not see that Mujazziz al-Mudliji (a physiognomist) looked at Zaid bin Harithah and Usama bin Zaid, and then said, 'These feet (of Zaid and Usama) are related to one another.'"[Agreed upon].
