‘Amr b. Shu'aib, on his father’s authority, said his grandfather told that God’s Messenger forbade two transactions in one bargain. It is transmitted in Sharh as-sunna.

He reported God’s Messenger as saying,“The proviso of a loan combined with a sale is not allowable, nor two conditions relating to one transaction, nor the profit arising from something which is not in one’s charge (An article belongs to the seller till the transaction is complete, and so long as it is still in his possession he is the one who gains any profit on it or bears any loss. The buyer cannot claim profit till he is in possession of the article nor selling what is not in your possession. Tirmidhi, Abu Dawud and Nasa’i transmitted it, Tirmidhi saying this is a sahih tradition.

Ibn ‘Umar said he used to sell camels at an-Naqi‘for dinars and take dirhams for them, and sell for dirhams and take dinars for them. He went to the Prophet and mentioned that to him, and he replied,“There is no harm in taking them at the current rate so long as you do not separate leaving something still to be settled.”Tirmidhi, Abu Dawud, Nasa’i and Darimi transmitted it.

Al-‘Adda’ b. Khalid b. Haudha brought out a document to this effect:This is what al-‘Adda’ b. Khalid b. Haudha brought from Muhammad, God’s Messenger. He bought from him a slave, or a slave woman, with no disease or wickedness, or anything unlawful*, a transaction between two Muslims. Tirmidhi transmitted it, saying this is a gharib tradition. * This might be bad character on the part of the slave or unlawful enslavement.

Anas said that God’s Messenger offered for sale a saddle-cloth (woolen cloth placed on a camel under the pack-saddle), and a drinking-vessel, saying,“Who will buy this saddle-cloth and drinking- vessel?”A man offered to take them for a dirham and the Prophet asked whether anyone would give more. A man offered him two dirhams and he sold them to him. Tirmidhi, Abu Dawud and Ibn Majah transmitted it.

Wathila b. al-Asqa' told that he heard God's Messenger say, "If anyone sells a defective article without drawing attention to it, he will remain under God’s anger," or,“the angels will continue to curse him.”Ibn Majah transmitted it.

Ibn ‘Umar reported God’s Messenger as saying,“If anyone buys palm-trees after they have been fecundated the fruit belongs to the seller unless the buyer makes a proviso; and if anyone buys a slave who possesses property his property belongs to the seller unless the buyer makes a proviso." Muslim transmitted it and Bukhari transmitted something to the same effect as the first part alone.

Jabir said:I was travelling on a camel of mine which had grown jaded when the Prophet passed by and struck it, with the result that it went as it had never done before. He then said,“Sell it to me for a wuqiya*”. I agreed, but made the stipulation that I should be allowed to ride it home. Then when I came to Medina I took the camel to him and he paid me its price in ready money. In a version he said,“He gave me its price and returned it to me." In a version by Bukhari he said to Bilal,“Pay him and give something extra," so he gave the money adding a qirat (A small coin, probably meaning here a sixteenth of a dirham). (Bukhari and Muslim.) *This and the more common form uqiya used below in the tradition from 'A'isha is an amount equivalent to forty dirhams.

‘A'isha said Barira came telling her she had arranged to buy her freedom for nine uqiyas; one to be paid annually, and asking her to help her. ‘A’isha replied,“If your people are willing that I should count them out to them all at one time and set you free, I shall do so, and I shall have the right to inherit from you." She went to her people, but they insisted that the right to inherit from her should be theirs, so God’s Messenger said,“Take her and set her free." He then stood up among the people, and after praising and extolling God, he said,“To proceed:What is the matter with people who make conditions which are not in God’s Book? Any condition which is not in God’s Book is worthless. Even if there are a hundred conditions, God’s decision is more valid and God's condition is more binding. The right of inheritance belongs only to the one who has set a person free.”(Bukhari and Muslim.)

Ibn ‘Umar said that God’s Messenger forbade selling or giving away the right to inheritance from a manumitted slave. (Bukhari and Muslim.)
