‘Uqba b. 'Amir reported Allah's Messenger ﷺ as saying, “If any Muslim performs ablution well, then stands and prays two rak'as, setting about their performance both inwardly and outwardly, he will be guaranteed paradise.” Muslim transmitted it.

‘Abdallah b. Mas'ud reported Allah's Messenger ﷺ as saying, “When two people who are arranging a business transaction disagree the decision rests with the seller, but the buyer has the right to choose whether he will confirm this*.” Tirmidhi transmitted it. In the version of Ibn Majah and Darimi he said, “When two people who are arranging a business transaction disagree, the commodity being present and is neither being able to prove his case, the decision rests with the seller, or they may both reject the transaction.” * The seller swears an oath to the effect that he is right. The buyer may either agree or swear in an oath that he is right. In the latter instance the qadi cancels the deal.

Abu Huraira reported Allah's Messenger ﷺ as saying, “If anyone rescinds a sale with a Muslim, Allah will cancel his slip* on the day of resurrection.” * Allah will forgive his fault. Abu Dawud and Ibn Majah transmitted it; and it occurs in Sharh as-sunna with the wording in al-Masabih on the authority of Shuraih ash-Shami in mursal form.

Abu Huraira reported Allah's Messenger ﷺ as saying, “A man of those who were before your time bought some real estate from another, and the buyer found in what he had bought a jar containing gold. The buyer told the other to take his gold from him as he had bought from him only the property and had not bought the gold from him, but the man who had sold the land said he had sold him the land and its contents. They brought the matter before another for decision and he asked whether they had any children. When one said he had a boy and the other said he had a girl, he told them to marry the boy to the girl and spend* some of the gold on them and give sadaqa.” *While the dual has been used with reference to the two men, the plural is used for “marry" and “spend’’. (Bukhari and Muslim.)

Ibn 'Abbas said that when Allah's Messenger ﷺ came to Medina they were paying one, two and three years in advance for fruits, so he said, “Those who pay in advance for anything must do so for a specified measure and weight with a specified time fixed.” (Bukhari and Muslim.)

'A’isha said that Allah's Messenger ﷺ bought some grain from a Jew to be paid at a specified time, and gave him a coat of mail of his as a pledge. (Bukhari and Muslim.)

She said that when Allah's Messenger ﷺ died his coat of mail was in pledge with a Jew for thirty sa's of barley. Bukhari transmitted it.

Abu Huraira reported Allah's Messenger ﷺ as saying, “An animal may be ridden for payment when it is in pledge and the milk of milch-camels may be drunk of payment when in pledge, payment being made by the one who rides and the one who drinks.” Bukhari transmitted it.

Sa'id b. al-Musayyib reported Allah's Messenger ﷺ as saying, “A pledge does not become lost to its owner when he does not redeem it in time. Any increase in its value goes to him and any loss must be borne by him.” Shafi'i transmitted it in mursal form, and something similar or something with a similar meaning with no discrepancy is transmitted on the authority of Abu Huraira with a fully connected isnad.

Ibn ‘Umar reported the Prophet (ﷺ) as saying, “The measure of capacity is that used by the people of Medina and the measure of weight is that used by the people of Mecca.” Abu Dawud and Nasa’i transmitted it.
