Sahih al-Bukhari

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.

A person came to the Prophet (ﷺ) and told him that he was always betrayed in purchasing. The Prophet (ﷺ) told him to say at the time of buying, "No cheating."

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 (ﷺ)! 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."

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."

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)

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).

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.'

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.'

I met `Abdullah bin `Amr bin Al-`As and asked him, "Tell me about the description of Allah's Messenger (ﷺ) which is mentioned in Torah (i.e. Old Testament.") He replied, 'Yes. By Allah, he is described in Torah with some of the qualities attributed to him in the Qur'an as follows: "O Prophet ! We have sent you as a witness (for Allah's True religion) And a giver of glad tidings (to the faithful believers), And a warner (to the unbelievers) And guardian of the illiterates. You are My slave and My messenger (i.e. Apostle). I have named you "Al-Mutawakkil" (who depends upon Allah). You are neither discourteous, harsh Nor a noisemaker in the markets And you do not do evil to those Who do evil to you, but you deal With them with forgiveness and kindness. Allah will not let him (the Prophet) Die till he makes straight the crooked people by making them say: "None has the right to be worshipped but Allah," With which will be opened blind eyes And deaf ears and enveloped hearts."

Allah's Messenger (ﷺ) said, "He who buys foodstuff should not sell it till he is satisfied with the measure with which he has bought it.

`Abdullah bin `Amr bin Haram died and was in debt to others. I asked the Prophet (ﷺ) to intercede with his creditors for some reduction in the debts. The Prophet (ﷺ) requested them (to reduce the debts) but they refused. The Prophet (ﷺ) said to me, "Go and put your dates (In heaps) according to their different kinds. The Ajwa on one side, the cluster of Ibn Zaid on another side, etc.. Then call me." I did that and called the Prophet (ﷺ) He came and sat at the head or in the middle of the heaps and ordered me. Measure (the dates) for the people (creditors)." I measured for them till I paid all the debts. My dates remained as it nothing had been taken from them. In other narrations, Jabir said; The Prophet (ﷺ) said, "He (i.e. `Abdullah) continued measuring for them till he paid all the debts." The Prophet (ﷺ) said (to `Abdullah), "Cut (clusters) for him (i.e. one of the creditors) and measure for him fully."

The Prophet (ﷺ) said, "Measure your foodstuff and you will be blessed."

The Prophet (ﷺ) said, "The Prophet (ﷺ) Abraham made Mecca a sanctuary, and asked for Allah's blessing in it. I made Medina a sanctuary as Abraham made Mecca a sanctuary and I asked for Allah's Blessing in its measures the Mudd and the Sa as Abraham did for Mecca.

Allah's Messenger (ﷺ) said, "O Allah bestow your blessings on their measures, bless their Mudd and Sa." The Prophet (ﷺ) meant the people of Medina.

that his father said. "I saw those, who used to buy foodstuff without measuring or weighing in the life time of the Prophet (ﷺ) being punished if they sold it before carrying it to their own houses."

Ibn `Abbas said, "Allah's Messenger (ﷺ) forbade the selling of foodstuff before its measuring and transferring into one's possession." I asked Ibn `Abbas, "How is that?" Ibn `Abbas replied, "It will be just like selling money for money, as the foodstuff has not been handed over to the first purchaser who is the present seller."

The Prophet (ﷺ) said, "He who buys foodstuff should not sell it till he has received it."

That the latter said, "Who has change?" Talha said, "I (will have change) when our storekeeper comes from the forest." Malik bin Aus narrated from `Umar bin Al-Khattab: Allah's Messenger (ﷺ) said, "The bartering of gold for gold is Riba (usury), except if it is from hand to hand and equal in amount, and wheat grain for wheat grain is usury except if it is form hand to hand and equal in amount, and dates for dates is usury except if it is from hand to hand and equal in amount, and barley for barley is usury except if it is from hand to hand and equal in amount."

The Prophet (ﷺ) forbade the selling of foodstuff before receiving it. I consider that all types of sellings should be done similarly.

The Prophet (ﷺ) said, "The buyer of foodstuff should not sell it before it has been measured for him." Isma`il narrated instead, "He should not sell it before receiving it."
