Abu Huraira reported God’s Messenger as saying, “If anyone rescinds a sale with a Muslim, God will cancel his slip* on the day of resurrection.”
* God 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.
‘Abdallah b. Mas'ud reported God’s Messenger 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 God’s Messenger 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’’.
I bought a slave and made him earn something for me, but afterwards I found a defect in him and so brought a case regarding him before ‘Umar b. ‘Abd al-‘Aziz, who decided in my favour that I should return him, but against me that I should return what he had earned. I therefore went to ‘Urwa and informed him, and he replied that he would go that evening to him and tell him he had been informed by ‘A'isha that God’s Messenger had given judgment in a similar case that any profit goes to the one who bears responsibility*. ‘Urwa went to him, and he gave judgment in my favour that I should receive the profit from the one for whom he had given the decision against me.
* al-Kharaj bid daman. After a sale any profit which accrues belongs to the buyer.
