Sahih al-Bukhari

I saw the people buy foodstuff randomly (i.e. blindly without measuring it) in the lifetime of Allah's Apostle and they were punished (by beating), if they tried to sell it before carrying it to their own houses.

Rarely did the Prophet (ﷺ) fail to visit Abu Bakr's house everyday, either in the morning or in the evening. When the permission for migration to Medina was granted, all of a sudden the Prophet (ﷺ) came to us at noon and Abu Bakr was informed, who said, "Certainly the Prophet (ﷺ) has come for some urgent matter." The Prophet (ﷺ) said to Abu Bark, when the latter entered "Let nobody stay in your home." Abu Bakr said, "O Allah's Messenger (ﷺ)! There are only my two daughters (namely `Aisha and Asma') present." The Prophet (ﷺ) said, "I feel (am informed) that I have been granted the permission for migration." Abu Bakr said, "I will accompany you, O Allah's Messenger (ﷺ)!" The Prophet (ﷺ) said, "You will accompany me." Abu Bakr then said "O Allah's Messenger (ﷺ)! I have two she-camels I have prepared specially for migration, so I offer you one of them. The Prophet (ﷺ) said, "I have accepted it on the condition that I will pay its price."

Allah's Messenger (ﷺ) said, "Do not urge somebody to return what he has already bought (i.e. in optional sale) from another seller so as to sell him your own goods."

Allah's Messenger (ﷺ) forbade the selling of things by a town dweller on behalf of a desert dweller; and similarly Najsh was forbidden. And one should not urge somebody to return the goods to the seller so as to sell him his own goods; nor should one demand the hand of a girl who has already been engaged to someone else; and a woman should not try to cause some other woman to be divorced in order to take her place.

A man decided that a slave of his would be manumitted after his death and later on he was in need of money, so the Prophet (ﷺ) took the slave and said, "Who will buy this slave from me?" Nu'aim bin `Abdullah bought him for such and such price and the Prophet (ﷺ) gave him the slave.

Allah's Messenger (ﷺ) forbade Najsh.

Allah's Messenger (ﷺ) forbade the sale called 'Habal-al-Habala which was a kind of sale practiced in the Pre- Islamic Period of ignorance. One would pay the price of a she-camel which was not born yet would be born by the immediate offspring of an extant she-camel.

Allah's Messenger (ﷺ) forbade the selling by Munabadha, i.e. to sell one's garment by casting it to the buyer not allowing him to examine or see it. Similarly he forbade the selling by Mulamasa. Mulamasa is to buy a garment, for example, by merely touching it, not looking at it.

The Prophet (ﷺ) forbade two kinds of dressing; (one of them) is to sit with one's legs drawn up while wrapped in one garment. (The other) is to lift that garment on one's shoulders. And also forbade two kinds of sale: Al-Limais and An-Nibadh.

Allah's Messenger (ﷺ) forbade selling by Mulamasa and Munabadha.

The Prophet (ﷺ) forbade two kinds of dresses and two kinds of sale, i.e., Mulamasa and Munabadha.

The Prophet (ﷺ) said, "Don't keep camels and sheep unmilked for a long time, for whoever buys such an animal has the option to milk it and then either to keep it or return it to the owner along with one Sa of dates." Some narrated from Ibn Seereen (that the Prophet (ﷺ) had said), "One Sa of wheat, and he has the option for three days." And some narrated from Ibn Seereen, " ... a Sa of dates," not mentioning the option for three days. But a Sa of dates is mentioned in most narrations.

Whoever buys a sheep which has not been milked for a long time, has the option of returning it along with one Sa of dates; and the Prophet (ﷺ) forbade going to meet the seller on the way (as he has no knowledge of the market price and he may sell his goods at a low price).

Allah's Messenger (ﷺ) said, "Do not go forward to meet the caravan (to buy from it on the way before it reaches the town). And do not urge buyers to cancel their purchases to sell them (your own goods) yourselves, and do not practice Najsh. A town dweller should not sell the goods for the desert dweller. Do not leave sheep unmilked for a long time, when they are on sale, and whoever buys such an animal has the option of returning it, after milking it, along with a Sa of dates or keeping it. it has been kept unmilked for a long period by the seller (to deceive others).

Allah's Messenger (ﷺ) said, "Whoever buys a sheep which has been kept unmilked for a long period, and milks it, can keep it if he is satisfied, and if he is not satisfied, he can return it, but he should pay one Sa of dates for the milk."

The Prophet (ﷺ) said, "If a slave-girl commits illegal sexual intercourse and it is proved beyond doubt, then her owner should lash her and should not blame her after the legal punishment. And then if she repeats the illegal sexual intercourse he should lash her again and should not blame her after the legal punishment, and if she commits it a third time, then he should sell her even for a hair rope."

Allah's Messenger (ﷺ) was asked about the slave-girl, if she was a virgin and committed illegal sexual intercourse. The Prophet (ﷺ) said, "If she committed illegal sexual intercourse, lash her, and if she did it a second time, then lash her again, and if she repeated the third time, then sell her even for a hair rope." Ibn Shihab said, "I don't know whether to sell her after the third or fourth offense."

Allah's Messenger (ﷺ) came to me and I told him about the slave-girl (Barirah) Allah's Messenger (ﷺ) said, "Buy and manumit her, for the Wala is for the one who manumits." In the evening the Prophet (ﷺ) got up and glorified Allah as He deserved and then said, "Why do some people impose conditions which are not present in Allah's Book (Laws)? Whoever imposes such a condition as is not in Allah's Laws, then that condition is invalid even if he imposes one hundred conditions, for Allah's conditions are more binding and reliable."

Aisha wanted to buy Barirah and he (the Prophet) went out for the prayer. When he returned, she told him that they (her masters) refused to sell her except on the condition that her Wala' would go to them. The Prophet (ﷺ) replied, 'The Wala' would go to him who manumits.' " Hammam asked Nafi` whether her (Barirah's) husband was a free man or a slave. He replied that he did not know.

I have given a pledge of allegiance to Allah's Messenger (ﷺ) for to testify that None has the right to be worshipped but Allah, and Muhammad is His Apostle, to offer prayers perfectly, to pay Zakat, to listen to and obey (Allah's and His Prophet's orders), and to give good advice to every Muslim.
