A hadith like this has been reported on the authority of Nafi' with the same chain of transmitters.

Ibn 'Umar (RA) said that Allah's Messenger (ﷺ) prohibited Shighar which means that a man gives his daughter in marriage on the condition that the other gives his daughter to him in marriage without any dower being paid by either.

A hadith like this has been narrated on the authority of'Abdullah bin 'Umar (RA) but with a slight variation of words.

Ibn 'Umar (RA) reported that Allah's Messenger (ﷺ) prohibited Shighar.

Ibn 'Umar (RA) reported Allah's Messenger (ﷺ) as having said: There is no Shighar in islam.

Ibn 'Umar (RA) reported that Allah's Messenger (ﷺ) said: When any one of you is invited to a feast, he should attend it.

Ibn 'Umar (RA) reported Allah's Apostle (ﷺ) as saying: When any one of you is invited to a feast, he should accept. 'Ubaidallah took this feast to be a wedding feast.

Ibn 'Umar (RA) reported Allah's Apostle (ﷺ) having said this: When any one of you is invited to a wedding feast, he should accept that.

Ibn 'Umar (RA) reported Allah's Messenger (may be upon him) having said this: Accept the feast, when you are invited.

Ibn 'Umar (RA) reported Allah's Apostle (ﷺ) as saying: When any one of you invites his brother, he (the latter) should accept his wedding feast, or any other like it.

Ibn 'Umar (RA) reported Allah's Messenger (ﷺ) having said: He who is invited to a wedding feast or like it, he should accept it.

Haaroon ibn Abd Allah narrated to me, Hajjaaj ibn Muhammad narrated to us, from Ibn Juraij, Musa ibn Uqbah informed me, from Naafi’, he said: I heard Abdullah ibn Umar say: The Messenger of Allah, peace and blessings be upon him, said: "Respond to this invitation when you are invited to it." He said: And Abdullah ibn Umar used to attend the invitation for a wedding and other than a wedding, and he would attend it while he was fasting.

Ibn 'Umar (RA) reported Allah's Apostle (ﷺ) having said: When you are invited to a feast (even though it is) the leg of the sheep, you should accept it.

Ibn 'Umar (RA) reported that he divorced his wife while she was menstruating during the lifetime of Allah's Messenger (ﷺ) . 'Umar bin Khattab (RA) asked Allah's Messenger (ﷺ) about it, whereupon Allah's Messenger (ﷺ) said: Command him ('Abdullah bin 'Umar) to take her back (and keep her) and pronounce divorce when she is purified and she again enters the period of menstruation and she is again purified (after passing the period of menses), and then if he so desires he may keep her and if he desires divorce her (finally) before touching her (without having an intercourse with her), for that is the period of waiting ('ldda) which God, the Exalted and Glorious, has commanded for the divorce of women.

Abdullah (b. 'Umar) reported that he divorced a wife of his with the pronouncement of one divorce during the period of menstruation. Allah's Messenger (ﷺ) commanded him to take her back and keep her until she was purified, and then she entered the period of menses in his (house) for the second time. And he should wait until she was purified of her menses. And then if he would decide to divorce her, he should do so when she was purified before having a sexual intercourse with her; for that was the 'Idda which Allah had commanded for the divorce of women. Ibn Rumh in his narration made this addition: When 'Abdullah was asked about it, he said to one of them: If you have divorced your wife with one pronouncement or two (then you can take her back), for Allah's Messenger (ﷺ) commanded me to do it; but if you have divorced her with three pronouncements, then she is forbidden for you until she married another husband, and you disobeyed Allah in regard to the divorce of your wife what HE had commanded you. (Muslim said: The word "one divorce" used by Laith is good.)

Ibn 'Umar (RA) reported: I divorced my wife during the lifetime of Allah's Messenger (ﷺ) when she was in the state of menses. 'Umar (RA) made a mention of it to Allah's Messenger (ﷺ) , whereupon he said: Command him to take her back and leave her (in that state) until she is purified. Then (let her) enter the period of second menses, and when she is purified, then divorce her (finally) before having a sexual intercourse with her, or retain her (finally). That is the 'Idda (the prescribed period) which Allah commanded (to be kept in view) while divorcing the women. 'Ubaidullah reported: I said to Nafi': What became of that divorce (pronounced within 'Idda)? He said: It was as one which she counted.

Ibn 'Umar (RA) reported that he divorced his wife during the period of menses. 'Umar (Allah be, pleased with him) asked Allah's Apostle (ﷺ) , and he commanded him ('Abdullah bin 'Umar) to have her back and then allow her respite until she enters the period of the second menses, and then allow her respite until she is purified, then divorce her (finally) before touching her (having a sexual intercourse with her), for that is the prescribed period which Allah commanded (to be kept in view) for divorcing the women. When Ibn 'Umar (RA) was asked about the person who divorces his wife in the state of menses, he said: If you pronounced one divorce or two, Allah's Messenger (ﷺ) had commanded him to take her back, and then allow her respite until she enters the period of the second menses, and then allow her respite until she is purified, and then divorce her (finally) before touching her (having a sexual intercourse with her); and if you have pronounced (three divorces at one and the same time) you have in fact disobeyed your Lord with regard to what He commanded you about divorcing your wife. But she is however (finally separated from you).

Safiyya bint Abu 'Ubaid reported on the authority of Hafsa or 'A'isha (Allah be pleased with thein) or from both of them that Allah's Messenger (may peace he upon him) said: It is not permissible for a woman believing in Allah and the Hereafter (or believing in Allah and His Messenger) that she should observe mourning for the dead beyond three days except in case of her husband.

A hadith like this is transmitted on the authority of Nafi'.

Safiyya bint Abu 'Ubaid reported that she heard Hafsa daughter of Umar (RA) , (and) wife of Allah's Prophet (ﷺ) , narrating a hadith like this from Allah's Apostle (ﷺ) , and she made this addition: "She should abstain from adorning herself (in case of the death of her husband) for four months and ten days."

Safiyya bint Abu 'Ubaid narrated this tradition of Allah's Prophet (ﷺ) on the authority of some wives of Allah's Apostle (ﷺ)

Nafi' reported on the authority of Ibn 'Umar (RA) that a person invoked curse on the wife during the lifetime of Allah's Messenger (ﷺ) , so he effected separation between them and traced the lineage of the son to his mother.

Ibn 'Umar (RA) reported: Allah's Messenger (ﷺ) asked a person from the Ansar and his wife to invoke curse (upon one another in order to testify to their truthfulness), and then effected separation between them.

Ibn 'Umar (RA) reported Allah's Messenger may peace be upon him) as saying: If anyone emancipates his share in a slave and has enough money to pay the full price for him, a fair price for the slave should be fixed, his partners given their shares, and the slave be thus emancipated, otherwise he is emancipated only to the extent of the first man's share.

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

Ibn 'Umar (RA) reported that 'A'isha decided to buy a slave-girl and then set her free, but her masters said: We are prepared to sell her to you on the condition that her right of inheritance would vest with us. She (Hadrat A'isha) made a mention of that to Allah's Messenger (ﷺ) whereupon he said: This should not stand in your way. The right of inheritance vests in one who emancipates.

'Abdullah (b. 'Umar) (RA) said that Allah's Messenger (ﷺ) forbade the transaction called habal al-habala.

Ibn 'Umar (RA) reported that the people of pre-Islamic days used to sell the meat of the slaughtered camel up to habal al-habala. And habal al-habala implies that a she-camel should give birth and then the (born one should grow young) and become pregnant. Allah's Messenger (ﷺ) forbade them that (this transaction).

Ibn 'Umar (RA) reported Allah's Messenger (ﷺ) as having said this: One amongst you should not enter into a transaction when another is bargaining.

Ibn 'Umar (RA) reported Allah's Messenger (ﷺ) as saying: A person should not enter into a transaction when his brother is already making a transaction and he should not make a proposal of marriage when his brother has already made a proposal except when lie gives permission.

Ibn 'Umar (RA) reported that Allah's Messenger (ﷺ) forbade the outbidding (against another).

Ibn 'Umar (RA) reported Allah's Messenger (ﷺ) as saying: He who buys foodgrain should not sell that before taking possession of it.

Ibn 'Umar (Allah be pleased with thcm) reported Allah's Messenger (ﷺ) as saying: When two persons enter into a transaction, each of them has the right to annul it so long as they are not separated and are together (at the place of transaction) ; or if one gives the other the right (to annul the transaction) But if one gives the other the option, the transaction is made on this condition (i. e. one has the right to annul the transaction), it becomes binding. And if they are separated after they have made the bargain and none of them annulled it, even then the transaction is binding.
