The people (of the Pre-Islamic Period) used to think that to perform `Umra during the months of Hajj was one of the major sins on earth. And also used to consider the month of Safar as a forbidden (i.e. sacred) month and they used to say, "When the wounds of the camel's back heal up (after they return from Hajj) and the signs of those wounds vanish and the month of Safar passes away then (at that time) `Umra is permissible for the one who wishes to perform it." In the morning of the 4th of Dhul- Hijja, the Prophet and his companions reached Mecca, assuming Ihram for Hajj and he ordered his companions to make their intentions of the Ihram for `Umra only (instead of Hajj) so they considered his order as something great and were puzzled, and said, "O Allah's Apostle! What kind (of finishing) of Ihram is allowed?" The Prophet replied, "Finish the Ihram completely like a non-Muhrim (you are allowed everything)."

'Ubaidullah was asked about Al Mahassab. 'Ubaidullah narrated: Nafi` said, 'Allah's Apostles, `Umar and Ibn `Umar camped there." Nafi` added, "Ibn `Umar used to offer the Zuhr and `Asr prayers at it (i.e. Al-Mahassab)." I think he mentioned the Maghrib prayer also. I said, "I don't doubt about `Isha' (i.e. he used to offer it there also), and he used to sleep there for a while. He used to say, 'The Prophet used to do the same.' "

"Allah's Apostle gave the land of Khaibar to the Jews to work on and cultivate and take half of its yield. Ibn `Umar added, "The land used to be rented for a certain portion (of its yield)." Nafi` mentioned the amount of the portion but I forgot it. Rafi` bin Khadij said, "The Prophet forbade renting farms." Narrated 'Ubaidullah Nafi` said: Ibn `Umar said: (The contract of Khaibar continued) till `Umar evacuated the Jews (from Khaibar).

The Prophet forbade that a man should be made to get up from his seat so that another might sit on it, but one should make room and spread out. Ibn `Umar disliked that a man should get up from his seat and then somebody else sit at his place.

Yahya related to me from Malik from Abd al-Malik ibn Qurayr from Muhammad ibn Sirin that a man came to Umar ibn al-Khattab and said, "I was racing a friend on horseback towards a narrow mountain trail and we killed a gazelle accidently and we were in ihram. What is your opinion?" Umar said to a man by his side, "Come, so that you and I may make an assessment." They decided on a female goat for him, and the man turned away saying, "This amir al-muminin cannot even make an assessment in the case of a gazelle until he calls a man to decide with him." Umar overheard the man's words and called him and asked him, "Do you recite surat al-Ma'ida?" and he said, "No." He said, "Then do you recognize this man who has taken the decision with me?" and he said, "No." He said, "If you had told me that you did recite surat al-Ma'ida, I would have dealt you a blow." Then he said, "Allah the Blessed, the Exalted says in His Book, 'as shall be judged by two men of justice among you, a sacrificial animal to reach the Kaba' (Sura 5 ayat 95), and this is Abd ar-Rahman ibn Awf."

`Umar said "O Allah's Apostle! I vowed to perform I`tikaf for one night in Al-Masjid-al-Haram, during the Pre-Islamic Period of ignorance (before embracing Islam). "The Prophet said, "Fulfill your vow." Ibn `Umar said to the lady, "Pray on her behalf." Ibn `Abbas said the same.

Ibn Umar narrated from Allah's Apostle (may peace be upon him) a hadlth like this.

who was one of those who used to write the Divine Revelation: Abu Bakr sent for me after the (heavy) casualties among the warriors (of the battle) of Yamama (where a great number of Qurra' were killed). `Umar was present with Abu Bakr who said, `Umar has come to me and said, The people have suffered heavy casualties on the day of (the battle of) Yamama, and I am afraid that there will be more casualties among the Qurra' (those who know the Qur'an by heart) at other battle-fields, whereby a large part of the Qur'an may be lost, unless you collect it. And I am of the opinion that you should collect the Qur'an." Abu Bakr added, "I said to `Umar, 'How can I do something which Allah's Apostle has not done?' `Umar said (to me), 'By Allah, it is (really) a good thing.' So `Umar kept on pressing, trying to persuade me to accept his proposal, till Allah opened my bosom for it and I had the same opinion as `Umar." (Zaid bin Thabit added:) `Umar was sitting with him (Abu Bakr) and was not speaking. me). "You are a wise young man and we do not suspect you (of telling lies or of forgetfulness): and you used to write the Divine Inspiration for Allah's Apostle. Therefore, look for the Qur'an and collect it (in one manuscript). " By Allah, if he (Abu Bakr) had ordered me to shift one of the mountains (from its place) it would not have been harder for me than what he had ordered me concerning the collection of the Qur'an. I said to both of them, "How dare you do a thing which the Prophet has not done?" Abu Bakr said, "By Allah, it is (really) a good thing. So I kept on arguing with him about it till Allah opened my bosom for that which He had opened the bosoms of Abu Bakr and `Umar. So I started locating Qur'anic material and collecting it from parchments, scapula, leaf-stalks of date palms and from the memories of men (who knew it by heart). I found with Khuza`ima two Verses of Surat-at-Tauba which I had not found with anybody else, (and they were):-- "Verily there has come to you an Apostle (Muhammad) from amongst yourselves. It grieves him that you should receive any injury or difficulty He (Muhammad) is ardently anxious over you (to be rightly guided)" (9.128) The manuscript on which the Qur'an was collected, remained with Abu Bakr till Allah took him unto Him, and then with `Umar till Allah took him unto Him, and finally it remained with Hafsa, `Umar's daughter.

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."

The Prophet said, "The example of a believer is like a green tree, the leaves of which do not fall." The people said. "It is such-and-such tree: It is such-and-such tree." I intended to say that it was the datepalm tree, but I was a young boy and felt shy (to answer). The Prophet said, "It is the date-palm tree." Ibn `Umar added, " I told that to `Umar who said, 'Had you said it, I would have preferred it to such-and such a thing."

This hadith has been narrated on the authority of Ibn Umar through another chain of transmitters (but with one alteration) that here Allah-o-Akbar is mentioned twice.
