Narrated Ibn `Abbas: `Ukaz, Majanna and Dhul-Majaz were markets in the Pre-Islamic period. When the people embraced Islam they considered it a sin to trade there. So, the following Holy Verse came:-- 'There is no harm for you if you seek of the bounty of your Lord (Allah) in the Hajj season." (2.198) Ibn `Abbas recited it like this.

Narrated `Amr: Here (i.e. in Mecca) there was a man called Nawwas and he had camels suffering from the disease of excessive and unquenchable thirst. Ibn `Umar went to the partner of Nawwas and bought those camels. The man returned to Nawwas and told him that he had sold those camels. Nawwas asked him, "To whom have you sold them?" He replied, "To such and such Sheikh." Nawwas said, "Woe to you; By Allah, that Sheikh was Ibn `Umar." Nawwas then went to Ibn `Umar and said to him, "My partner sold you camels suffering from the disease of excessive thirst and he had not known you." Ibn `Umar told him to take them back. When Nawwas went to take them, Ibn `Umar said to him, "Leave them there as I am happy with the decision of Allah's Messenger (ﷺ) that there is no oppression . "

Narrated Abu Qatada: We set out with Allah's Messenger (ﷺ) in the year of Hunain, (the Prophet (ﷺ) gave me an armor). I sold that armor and bought a garden in the region of the tribe of Bani Salama and that was the first property I got after embracing Islam.

Narrated Abu Musa: Allah's Messenger (ﷺ) said, "The example of a good companion (who sits with you) in comparison with a bad one, is like that of the musk seller and the blacksmith's bellows (or furnace); from the first you would either buy musk or enjoy its good smell while the bellows would either burn your clothes or your house, or you get a bad nasty smell thereof."

Narrated Anas bin Malik: Abu Taiba cupped Allah's Messenger (ﷺ) so he ordered that he be paid one Sa of dates and ordered his masters to reduce his tax (as he was a slave and had to pay a tax to them).

Narrated `Abdullah bin `Umar: Once the Prophet (ﷺ) sent to `Umar a silken two-piece garment, and when he saw `Umar wearing it, he said to him, "I have not sent it to you to wear.

Narrated Aisha: (mother of the faithful believers) I bought a cushion with pictures on it. When Allah's Messenger (ﷺ) saw it, he kept standing at the door and did not enter the house. I noticed the sign of disgust on his face, so I said, "O Allah's Messenger! I repent to Allah and H is Apostle . (Please let me know) what sin I have done." Allah's Messenger (ﷺ) said, "What about this cushion?" I replied, "I bought it for you to sit and recline on." Allah's Messenger (ﷺ) said, "The painters (i.e. owners) of these pictures will be punished on the Day of Resurrection. It will be said to them, 'Put life in what you have created (i.e. painted).' " The Prophet (ﷺ) added, "The angels do not enter a house where there are pictures."

Narrated Ibn `Umar: Allah's Messenger (ﷺ) said, "The seller and the buyer have the option of canceling or confirming the deal unless they separate, or one of them says to the other, 'Choose (i.e. decide to cancel or confirm the bargain now)." Perhaps he said, 'Or if it is an optional sale.' " Ibn `Umar, Shuraih, Ash-Shu`bi, Tawus, Ata, and Ibn Abu Mulaika agree upon this judgment.

Narrated `Abdullah bin `Umar: Allah's Messenger (ﷺ) said, "Both the buyer and the seller have the option of canceling or confirming a bargain unless they separate, or the sale is optional." (See Hadith No.320).

Narrated Ibn `Umar: The Prophet (ﷺ) said, "No deal is settled and finalized unless the buyer and the seller separate, except if the deal is optional (whereby the validity of the bargain depends on the stipulations agreed upon).

Narrated Hakim bin Hizam: The Prophet (ﷺ) said, "Both the buyer and the seller have the option of canceling or confirming the bargain unless they separate." The sub-narrator, Hammam said, "I found this in my book: 'Both the buyer and the seller give the option of either confirming or canceling the bargain three times, and if they speak the truth and mention the defects, then their bargain will be blessed, and if they tell lies and conceal the defects, they might gain some financial gain but they will deprive their sale of (Allah's) blessings."

Narrated Ibn 'Umar (ra) : We were accompanying the Prophet (ﷺ) on a journey and I was riding an unmanageable camel belonging to 'Umar (ra), and I could not bring it under my control. So, it used to go ahead of the party and 'Umar would check it and force it to retreat, and again it went ahead and again 'Umar forced it to retreat. The Prophet (ﷺ) asked 'Umar to sell that camel to him. 'Umar replied, "It is for you O Allah's Messenger (ﷺ) !" Allah's Messenger (ﷺ) told 'Umar to sell that camel to him (not to give it as gift). So, 'Umar sold it to Allah's Messenger (ﷺ). Then the Prophet (ﷺ) said to 'Abdullah bin 'Umar "This camel is for you O 'Abdullah (as a present) and you could do with it whatever you like."

Narrated 'Abdullah bin 'Umar (ra): I bartered my property in Khaibar to 'Uthman (chief of the faithful believers) for his property in Al-Wadi. When we finished the deal, I left immediately and got out of his house lest he should cancel the deal, for the tradition was that they buyer and the seller had the option of canceling the bargain unless they separated. When out deal was completed, I came to know that I have been unfair to 'Uthman, for by selling him my land I caused him to be in a land of Thamud, at a distance of three days journey from Al-Madina, while he made me neared to Al-Madina, at a distance of three days journey from my former land.

Narrated `Aisha: Allah's Messenger (ﷺ) said, "An army will invade the Ka`ba and when the invaders reach Al-Baida', all the ground will sink and swallow the whole army." I said, "O Allah's Messenger! How will they sink into the ground while amongst them will be their markets (the people who worked in business and not invaders) and the people not belonging to them?" The Prophet (ﷺ) replied, "all of those people will sink but they will be resurrected and judged according to their intentions."

Narrated Abu Huraira: Allah's Messenger (ﷺ) said, "The congregational prayer of anyone amongst you is more than twenty (five or twenty seven) times in reward than his prayer in the market or in his house, for if he performs ablution completely and then goes to the mosque with the sole intention of performing the prayer, and nothing urges him to proceed to the mosque except the prayer, then, on every step which he takes towards the mosque, he will be raised one degree or one of his sins will be forgiven. The angels will keep on asking Allah's forgiveness and blessings for everyone of you so long as he keeps sitting at his praying place. The angels will say, 'O Allah, bless him! O Allah, be merciful to him!' as long as he does not do Hadath or a thing which gives trouble to the other." The Prophet (ﷺ) further said, "One is regarded in prayer so long as one is waiting for the prayer."

Narrated Anas bin Malik: While the Prophet (ﷺ) was in the market, somebody, called, "O Abul-Qasim." The Prophet (ﷺ) turned to him. The man said, "I have called to this (i.e. another man)." The Prophet (ﷺ) said, "Name yourselves by my name but not by my Kunya (name)." (In Arabic world it is the custom to call the man as the father of his eldest son, e.g. Abul-Qasim.) (See Hadith No. 737, Vol. 4)

Narrated Anas: A man at Al-Baqi' called, "O Abul-Qasim!" The Prophet (ﷺ) turned to him and the man said (to the Prophet ), "I did not intend to call you." The prophet said, "Name yourselves by my name but not by my Kunya (name).

Narrated Abu Huraira Ad-Dausi: Once the Prophet (ﷺ) went out during the day. Neither did he talk to me nor I to him till he reached the market of Bani Qainuqa and then he sat in the compound of Fatima's house and asked about the small boy (his grandson Al-Hasan) but Fatima kept the boy in for a while. I thought she was either changing his clothes or giving the boy a bath. After a while the boy came out running and the Prophet (ﷺ) embraced and kissed him and then said, 'O Allah! Love him, and love whoever loves him.'

Narrated Nafi`: Ibn `Umar told us that the people used to buy food from the caravans in the lifetime of the Prophet. The Prophet (ﷺ) used to forbid them to sell it at the very place where they had purchased it (but they were to wait) till they carried it to the market where foodstuff was sold. Ibn `Umar said, 'The Prophet (ﷺ) also forbade the reselling of foodstuff by somebody who had bought it unless he had received it with exact full measure.'
