Narrated Abdullah ibn AbuAwfa ibn AbuAwfa al-Aslami:

We made a journey to Syria on an expedition along with the Messenger of Allah (ﷺ). The Nabateans of Syria came to us and we paid in advance to them (in a salam contract) in wheat and olive oil at a specified rate and for a specified time. He asked (by the people): you might have contracted with him who had these things in his possession? He replied: We did not ask them.

Narrated Abdullah ibn Umar:

A man paid in advance for a palm-tree. It did not bear fruit that year. They brought their case for decision to the Prophet (ﷺ). He said: for which do you make his property lawful? He then said: Do not pay in advance for a palm-tree till they (the fruits) were clearly in good condition.

Narrated AbuSa'id al-Khudri:

The Prophet (ﷺ) said: If anyone pays in advance he must not transfer it to someone else before he receives it.

The tradition mentioned above has also been related by al-'Amash to the same effect through a different chain of narrators. This version adds: "He used: 'Not purify them ; grievously will be their penalty.'"

He said about (selling) the goods: I swear by Allah, I was given (the price) so and so for it. The other man considered it to be correct and bought it.

Narrated A man:

A man from the immigrants of the Companions of the Prophet (ﷺ) said: I participated in battle three times along with the Prophet (ﷺ). I heard him say: Muslims have common share in three (things). grass, water and fire.

Narrated Ibn 'Umar:

During the time of Messenger of Allah (ﷺ) we used to buy grain, and he sent a man to us who ordered us to move it from the spot where we had bought it to some other place, before we sold it without weighing or measuring it.

Ibn 'Umar said:

They (the people) used to buy grain in the upper part of the market in the same spot without measuring or weighing it. The Messenger of Allah (ﷺ) forbade them to sell it there before removing it.

Narrated Abdullah ibn Umar:

The Messenger of Allah (ﷺ) forbade to sell grain which one buys by measurement until one receives it in full.

Narrated Ibn Umar:

I bought olive oil in the market. When I became its owner, a man met me and offered good profit for it. I intended to settle the bargain with him, but a man caught hold of my hand from behind. When I turned I found that he was Zayd ibn Thabit. He said: Do not sell it on the spot where you have bought it until you take it to your house, for the Messenger of Allah (ﷺ) forbade to sell the goods where they are bought until the tradesmen take them to their houses.

Narrated Anas ibn Malik:

During the time of the Messenger of Allah (ﷺ) a man used to buy (goods), and he was weak in his intellect. His people came to the Prophet of Allah (ﷺ) and said: Prophet of Allah, stop so-and-so (to make a bargain) for he buys (goods), but he is weak in his intellect. So the Prophet (ﷺ) called on him and forbade him to make a bargain. He said: Prophet of Allah, I cannot keep away myself from business transactions. Thereupon the Messenger of Allah (ﷺ) said: If you cannot give up making a bargain , then say: Take , and give, and there is no attempt to deceive.

Narrated 'Amr b. Suh'aib:

On his father's authority, said that his grandfather told that the Messenger of Allah (ﷺ) forbade the type of transactions in which earnest money was paid.

Malik said: This means, as we think--Allah better knows-that a man buys a slave or hires an animal, and he says: I give you a dinar on condition that if I give up the transaction or hire, what I gave you is yours.

Narrated Hakim ibn Hizam:

Hakim asked (the Prophet): Messenger of Allah, a man comes to me and wants me to sell him something which is not in my possession. Should I buy it for him from the market? He replied: Do not sell what you do not possess.

On his father's authority, said that his grandfather 'Abd Allah b. 'Amr reported the Messenger of Allah (ﷺ) as saying: The proviso of a loan combined with a sale is not allowable, nor two conditions relating to one transaction, nor profit arising from something which is not in one's charge, nor selling what is not in your possession.

Narrated Uqbah ibn Amir:

The Prophet (ﷺ) said: The contractual obligation of a slave is three days.

The tradition mentioned above has also been transmitted by Qatadah through a different chain of narrators to the same effect. This version adds: "If he finds defect (in the slave) within three days, he may return it without evidence; if he finds a defect after three days, he will be required to produce evidence that he (the slave) had the defect when he bought it."

Abu Dawud said: This explanation is from the words of Qatadah.

He disputed me and the case of his claim to his share in the earnings to a judge, who ordered me to return the earnings (i.e. his share) to him. I then came to Urwah ibn az-Zubayr, and related the matter to him. Urwah then came to him and narrated to him a tradition from the Messenger of Allah (ﷺ) on the authority of Aisha: Profit follows responsibility.

Narrated Aisha, Ummul Mu'minin:

A man bought a slave, and he remained with him as long as Allah wished him to remain. He then found defect in him. He brought his dispute with him to the Prophet (ﷺ) and he returned him to him. The man said: Messenger of Allah, my slave earned some wages. The Messenger of Allah (ﷺ) then said: Profit follows responsibility.

Abu Dawud said: This chain of narrators (of this version) is not reliable.

Narrated Abdullah ibn Mas'ud:

Muhammad ibn al-Ash'ath said: Al-Ash'ath bought slaves of booty from Abdullah ibn Mas'ud for twenty thousand (dirhams. Abdullah asked him for payment of their price. He said: I bought them for ten thousand (dirhams). Abdullah said: Appoint a man who may adjudicate between me and you. Al-Ash'ath said: (I appoint) you between me and yourself.
