Ibn 'Umar (RA) reported that Allah's Messenger (may peace be, upon him) ordered the killing of dogs except the dog tamed for hunting, or watching of the herd of sheep or other domestic animals. It was said to Ibn 'Umar (RA) that Abu Hurairah (RA) talks of (exception) about the dog for watching the field, whereupon he said: Since Abu Hurairah (RA) possessed land.

Ibn 'Umar reported Allah's Messenger (ﷺ) as saying He who kept a dog other than one meant for hunting or for watching the herd lost out of his deeds (equal to) two qirat every day.

Ibn 'Umar reported that 'Umar bin al-Khattib (RA) donated a horse in the path of Allah and (later on) he found it being sold, and he decided to buy that. He asked the Messenger of Allah (ﷺ) about it, whereupon he (the Holy prophet) said: Don't buy that and do not get back what you gave in charity.

This hadith has been narrated on the authority of Ibn 'Umar (RA) through another chain of transmitters.

Ibn 'Umar (RA) reported Allah's Messenger (ﷺ) as saying: It is the duty of a Muslim who has something which is to be given as a bequest not to have it for two nights without having his will written down regarding it.

A hadith like this has been narrated on the authority of Nafi', who based his narrations of the words of Ibn 'Umar but with a slight variation of words.

Salim reported on the authority of his father (''Abdullah bin 'Umar (RA) ) that he (his father) had heard Allah's Messenger (ﷺ) as saying: It is not proper for a Muslim who has got something to bequeathe to spend even three nights without having his will written down with him regarding it. 'Abdullah bin 'Umar (RA) said: Ever since I heard Allah's Messenger (ﷺ) say this I have not spent a night without having my will (written) along with me.

Ibn 'Umar (RA) reported: Umar acquired a land at Khaibar. He came to Allah's Apostle (ﷺ) and sought his advice in regard to it. He said: Allah's Messenger, I have acquired land in Khaibar. I have never acquired property more valuable for me than this, so what do you command me to do with it? Thereupon he (Allah's Apostle) (ﷺ) said: If you like, you may keep the corpus intact and give its produce as Sadaqa. So 'Umar gave it as Sadaqa declaring that property must not be sold or inherited or given away as gift. And Umar devoted it to the poor, to the nearest kin, and to the emancipation of slaves, aired in the way of Allah and guests. There is no sin for one, who administers it if he eats something from it in a reasonable manner, or if he feeds his friends and does not hoard up goods (for himself). He (the narrator) said: I narrated this hadith to Muhammad, but as I reached the (words) "without hoarding (for himself) out of it." he (Muhammad' said: "without storing the property with a view to becoming rich." Ibn 'Aun said: He who read this book (pertaining to Waqf) informed me that in it (the words are) "without storing the property with a view to becoming rich."

'Umar reported: I acquired land from the lands of Khaibar. I came to Allah's Messenger (ﷺ) and said: I have acquired a piece of land. Never have I acquired land more loved by me and more cherished by me than this. The rest of the hadith is the same, but he made no mention of this: "I narrated it to Muhammad" and what follows.

'Abdullah bin 'Umar (RA) reported: Allah's Messenger (may peace he upon him) singled out one day forbidding us to take vows and said: It would not avert anything; it is by which something is extracted from the miserly person.

Ibn 'Umar (RA) reported Allah's Apostle (ﷺ) as saying: The vow neither hastens anything nor defers anything, but is the means whereby (something) is extracted from the miserly person.

Ibn 'Umar (RA) reported that Allah's Apostle (ﷺ) forbade (people) taking vows, and said: It does not (necessarily) bring good (in the form of substantial, and tangible results), but it is the meant whereby something is extracted from the miserly persons.

'Umar bin al-Khattab reported Allah's Messenger (ﷺ) as saying: Allah, the Great and Majestic, forbids you to swear by your fathers. Umar said: By Allah. I have never sworn (by my father) since I heard Allah's Messenger (ﷺ) forbidding it mentioning them "on my behalf" nor on behalf of someone else.

Umar) reported that Allah's Messenger (ﷺ) found, Umar bin al-Khattab amongst the riders and he was taking oath by his father Allah's Messenger (ﷺ) called them (saying): Our Allah, the Exalted and Majestic, has forbidden that you take oath by your father. He who has to take an oath, he must take it by Allah or keep quiet.

This hadith is narrated on the authority of Ibn 'Umar (RA) through another chain of transmitters.

Ibn 'Umar heard Allah's Messenger (ﷺ) as saying: He who has to take an oath, he must not take oath but by Allah. The Quraish used to take oath by their fathers. So he (the Holy Prophet) said: Do not take oath by your fathers.

Book 015, Number 4072: Ibn 'Umar reported that Umar (b. Khattab) said: Messenger of Allah, I had taken a vow during the days of Ignorance (Jahiliyya) that I would observe I'tikaf for a night in the Sacred Mosque. He (the Holy Prophet) said: Fulfil your vow.

'Abdullah bin 'Umar reported that 'Umar bin Khattab asked the Messenger of Allah (ﷺ) as he was at ji'rana (a town near Makkah) on his way back from Ta'if: Messenger of Allah, I had taken a vow during the days of Ignorance that I would observe I'tikaf for one day in the Sacred Mosque. So what is your opinion? He said: Go and observe I'tikaf for a day. And Allah's Messenger (ﷺ) gave him a slave girl out of the one-fifth (of the spoils of war meant for the Holy Prophet). And when Allah's Messenger (ﷺ) set the war prisoners free, 'Umar bin Khattab heard their voice as they were saying: Allah's Messenger (ﷺ) has set us free. He (Hadrat 'Umar) said: What is this? They said: Allah's Messenger (ﷺ) has set free the prisoners of war (which had fallen to the lot of people). Thereupon he (Hadrat 'Umar) said:'Abdullah, go to that slave-girl and set her free.

He said: He did not enter into the state of Ihram from that (place), and Umar had taken a vow of observing I'tikaf for a night during the days of Ignorance. The rest of the hadith is the same.

This hadith has been transmitted on the authority of Ibn 'Umar (RA) through another chain of transmitters but with a slight variation of words.

Zadhan Abl Umar reported: I came to Ibn 'Umar as he had granted freedom to a slave. He (the narrator further) said: He took hold of a wood or something like it from the earth and said: It (freedom of a slave) has not the reward evert equal to it, but the fact that I heard Allah's Messenger (ﷺ) say: He who slaps his slave or beats him, the expiation for it is that he should set him free.

Zadhan reported that Ibn 'Umar (RA) called his slave and he found the marks (of beating) upon his back. He said to him: I have caused you pain. He said: No. But he ( Ibn 'Umar (RA) ) said: You are free. He then took hold of something from the earth and said: There is no reward for me even to the weight equal to it. I heard Allah's Messenger (ﷺ) as saying: He who beats a slave without cognizable offence of his or slaps him (without any serious fault), then expiation for it is that he should set him free.

Ibn 'Umar (RA) reported Allah's Messenger (ﷺ) as saying: When a slave looks to the welfare of his master and worships Allah well, he has two rewards for him.

This hadith has been narrated on the authority of Ibn 'Umar through another chain of transmitters.

Ibn 'Umar reported Allah's Messenger (ﷺ) as saying: He who gives up his share in a slave, and has enough money to pay the full price of the slave, then full emancipation devolves upon him; but if he has not the money, then he emancipated what he emancipated.

Ibn 'Umar reported Allah's Messenger (ﷺ) as saying: He who emancipates his share in the slave, it is his responsibility to secure full freedom for him provided he (the slave) has enough money to pay the (remaining) price, but if he has not so much money he would be emancipated to the extent that the first man emancipated.

'Abdullah bin 'Umar reported Allah's Messenger (ﷺ) as saying: He who gives up his share in a slave, and he has money enough to meet the full price, a fair price for him should be fixed; otherwise be has emancipated him to the extent that he has emancipated.

This hadith has been narrated through another chain of transmitters with a slight variation of words.

Salim bin 'Abdullah reported on the authority of his father that Allah's Apostle (ﷺ) said: He who emancipates a slave (shared) by him and another one, his full price may be justly assessed from his wealth, neither less nor more, and he (the slave) would be emancipated if he (the partner) would be solvent enough (to forgo the amount of his share).
