Narrated Nafi`: That Ubaidullah bin `Abdullah and Salim bin `Abdullah informed him that they told Ibn `Umar when Ibn Az-Zubair was attacked by the army, saying "There is no harm for you if you did not perform Hajj this year. We are afraid that you may be prevented from reaching the Ka`ba." Ibn `Umar said "We set out with Allah's Apostle and the non-believers of Quraish prevented us from reaching the Ka`ba, and so the Prophet slaughtered his Hadi and got his head shaved." Ibn `Umar added, "I make you witnesses that I have made `Umra obligatory for me. And, Allah willing, I will go and then if the way to Ka`ba is clear, I will perform the Tawaf, but if I am prevented from going to the Ka`ba then I will do the same as the Prophet did while I was in his company." Ibn `Umar then assumed Ihram for Umra from Dhul-Hulaifa and proceeded for a while and said, "The conditions of `Umra and Hajj are similar and I make you witnesses that I have made `Umra and Hajj obligatory for myself." So, he did not finish the Ihram till the day of Nahr (slaughtering) came, and he slaughtered his Hadi. He used to say, "I will not finish the Ihram till I perform the Tawaf, one Tawaf on the day of entering Mecca (i.e. of Safa and Marwa for both `Umra and Hajj).

Narrated Salim: (Abdullah) bin `Umar used to say, "Is not (the following of) the tradition of Allah's Apostle sufficient for you? If anyone of you is prevented from performing Hajj, he should perform the Tawaf of the Ka`ba and between As-Safa and Al-Marwa and then finish the Ihram and everything will become legal for him which was illegal for him (during the state of Ihram) and he can perform Hajj in a following year and he should slaughter a Hadi or fast in case he cannot afford the Hadi."

Narrated Nafi`: That `Abdullah and Salim said to `Abdullah bin `Umar, "(You should not go for Hajj this year)." `Abdullah bin `Umar replied, "We set out with the Prophet (to Mecca for performing `Umra) and e infidels of Quraish prevented us from reaching the Ka`ba. Allah's Apostle slaughtered his Budn (camels for sacrifice) and got his head shaved."

Narrated Nafi`: When `Abdullah bin `Umar set out for Mecca with the intentions performing `Umra in the period of afflictions, he said, "If I should be prevented from reaching the Ka`ba, then I would do the same as we did while in the company of Allah's Apostle ." So, he assumed the Ihram for `Umra since the Prophet had assumed the Ihram for `Umra in the year of Al-Hudaibiya. Then `Abdullah bin `Umar thought about it and said, "The conditions for both Hajj and `Umra are similar." He then turned towards his companions and said, "The conditions of both Hajj and `Umra are similar and I make you witnesses that I have made the performance of Hajj obligatory for myself along with `Umra." He then performed one Tawaf (between As-Safa and Al-Marwa) for both of them (i.e. Hajj and (`Umra) and considered that to be sufficient for him and offered a Hadi.

Narrated `Abdullah bin `Umar: Allah's Apostle said, "It is not sinful of a Muhrim to kill five kinds of animals."

Narrated `Abdullah bin `Umar: A person stood up and asked, "O Allah's: Apostle! What clothes may be worn in the state of Ihram?" The Prophet replied, "Do not wear a shirt or trousers, or any headgear (e.g. a turban), or a hooded cloak; but if somebody has no shoes he can wear leather stockings provided they are cut short off the ankles, and also, do not wear anything perfumed with Wars or saffron, and the Muhrima (a woman in the state of Ihram) should not cover her face, or wear gloves."

Narrated `Abdullah: Allah's Apostle was asked what sort of clothes a Muhrim should wear. He replied, "He should not wear a shirt, turbans, trousers, a hooded cloak, or a dress perfumed with saffron or Wars; and if slippers are not available he can wear Khuffs (socks made from thick fabric or leather) but he should cut them so that they reach below the ankles.

Narrated Ibn `Umar: The Prophet observed the fast on the 10th of Muharram ('Ashura), and ordered (Muslims) to fast on that day, but when the fasting of the month of Ramadan was prescribed, the fasting of the 'Ashura' was abandoned. `Abdullah did not use to fast on that day unless it coincided with his routine fasting by chance.

Narrated Ibn `Umar: I heard Allah's Apostle saying, "When you see the crescent (of the month of Ramadan), start fasting, and when you see the crescent (of the month of Shawwal), stop fasting; and if the sky is overcast (and you can't see it) then regard the month of Ramadan as of 30 days."

Narrated `Abdullah bin `Umar: Allah's Apostle mentioned Ramadan and said, "Do not fast unless you see the crescent (of Ramadan), and do not give up fasting till you see the crescent (of Shawwal), but if the sky is overcast (if you cannot see it), then act on estimation (i.e. count Sha'ban as 30 days).

Narrated `Abdullah: The Prophet fasted for days continuously; the people also did the same but it was difficult for them. So, the Prophet forbade them (to fast continuously for more than one day).

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 Apostle that there is no oppression . "

Narrated `Abdullah bin `Umar: Once the Prophet 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 Ibn `Umar: The Prophet said, "The buyer and the seller have the option to cancel or confirm the bargain before they separate from each other or if the sale is optional." Nafi` said, "Ibn `Umar used to separate quickly from the seller if he had bought a thing which he liked."

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 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 `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."
