Sahih Muslim

Abu Huraira (Allah be pleased with him) reported that Allah's Messenger (ﷺ) forbade the combining of a woman in marriage with her father's sister, or with her mother's sister, or that a woman should ask for divorce for her sister in order to deprive her of what belongs to her. Allah, the Exalted'and Majestic, is her Sustainer too.

Abu Huraira (Allah be pleased with him) reported that Allah's Messenger (ﷺ) forbade to combine a woman and her father's sister, and a woman and her mother's sister.

A hadith like this has been transmitted on the authority of Amr b. Dinar

I heard 'Uthman b. 'Affan say that Allah's Messenger (ﷺ) had stated: A Muhrim must neither marry himself, nor arrange the marriage of another one, nor should he make the proposal of marriage.

Umar b. Ubaidullah b. Ma'mar sent me to Aban b. Uthman as he wanted to make the proposal of the marriage of his son with the daughter of Shaiba b. Uthman. He (Aban b. Uthman) was at that time (busy) in the season of Pilgrimage. He said: I deem him to be a man of the desert (for it is a common thing) that a Muhrim can neither marry, nor is he allowed to be married to anyone. It is Uthman (b. Affan) who reported this to us from Allah's Messenger (ﷺ).

A Muhrim should neither marry himself, nor should he be got married to anyone, nor should he make the proposal of marriage.

A Muhrim should neithermarry (in that state) nor make the proposal of marriage.

I intend to marry Talha b. 'Umar and I earnestly desire you to be present there (in this ceremony of marriage). Aban said to him: I find you a block-headed 'Iraqi. I heard 'Uthman b. 'Affan say that Allah's Messenger (ﷺ) said: A Muhrim should not marry.

" I narrated it to Zuhri and he said: Yazid b. al-Asamm (Allah be pleased with him) told me that he (the Holy Prophet) married her when he was not a muhrim."

Allah's Messenger. (ﷺ) married Maimuna while he was a Muhrim.

Maimuna daughter of al-Harith narrated to me that Allah's Messenger (ﷺ) married her and he was not in the state of Ihram. And she (Maimuna) was my mother's sister and that of Ibn 'Abbas (Allah be pleased with them).

None amongst you should outbid another in a transaction, nor should he make proposals of marriage upon the proposal made by someone else.

A person should not enter into a transaction when his brother (had already entered into but not finalised), and he should not make proposal of marriage upon the proposal already made by his brother, until he permits it.

The above hadith has been narrated by Ibn Umar through another chain.

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

" The person should not purchase in opposition to his brother."

Do not outbid in a sale in order to ensnare. No man should enter into a transaction in which his brother has already entered, and no dweller of the town should sell on behalf of the villager. And no man should make a proposal of marriage which his brother has already made and no woman should ask for the divorce of another (co-wife) in order to deprive her of what belongs to her.

A hadith like this has been narrated on the authority of Zuhri with the same chain of transmitters but with a slight alteration.

The Muslim should not purchase in opposition to his brother, and he should not make the proposal of marriage on the proposal already made by his brother.

This hadith has been narrated on the authority of Abu Huraira (Allah be pleased with him) through another chain of transmitters.
