Narrated Ibn `Umar: Allah's Apostle said, "Both the buyer and the seller have the option of canceling or confirming the bargain, as long as they are still together, and unless they separate or one of them gives the other the option of keeping or returning the goods and a decision is concluded then, in which case the bargain is considered final. If they separate after the bargain and none of them has rejected it, then the bargain is rendered final."

Narrated Ibn `Umar: The Prophet 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 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."

Tawoos said regarding the person who, after the consent of the (second party), buys some goods from him and then sells them, and the seller does not object, then this sale becomes binding. And its profit will also belong to the buyer.

Narrated Ibn 'Umar (ra): We were accompanying the Prophet (saws) 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 (saws) asked 'Umar to sell that camel to him. 'Umar replied, "It is for you O Allah's Messenger!" Allah's Messenger (saws) told 'Umar to sell that camel to him (not to give it as gift). So, 'Umar sold it to Allah's Messenger (saws). Then the Prophet (saws) 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 Al-Wadi to 'Uthman (chief of the faithful believers) for his property in Khaibar. 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 `Abdullah bin `Umar: A person came to the Prophet and told him that he was always betrayed in purchasing. The Prophet told him to say at the time of buying, "No cheating."

And Abdur-Rahman bin Awf, may Allah be pleased with him, said that when we came to Madinah, I asked (my Islamic brother) if there was any market here, and he said, "The market of Qaynuqa'." Anas, may Allah be pleased with him, narrated that Abdur-Rahman bin Awf, may Allah be pleased with him, said, "Show me the market." And Umar, may Allah be pleased with him, once said that trading in the market kept me preoccupied.

Narrated `Aisha: Allah's Apostle 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 Apostle! 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 replied, "all of those people will sink but they will be resurrected and judged according to their intentions."

Narrated Abu Huraira: Allah's Apostle 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 further said, "One is regarded in prayer so long as one is waiting for the prayer."
