The Book of Marriage
كتاب النكاح
Chapter 4: The prohibition of being married to a woman and her paternal aunt or maternal aunt at the same time
that Allah's Messenger (ﷺ) forbade combining of four women in marriage: a woman with her father's sister, and a woman with her mother's sister.
I heard Allah's Messenger (ﷺ) say: Father's sister should not be combined with her brother's daughter, nor the daughter of a sister with her mother's sister.
So we regarded the paternal aunt of her (wife's) father and the maternal aunt of her (wife's) father at the same level.
One should not combine in marriage a woman with her father's sister, or her mother's sister.
A hadith like this has been narrated on the authority of Abu Huraira (Allah be pleased with him) through another chain of transmitters.
A man must not make proposal of marriage to a woman when his brother has done so already. And he must not offer a price for a thing for which his brother had already offered a price; and a woman must not be combined in marriage with her father's sister, nor with her mother's sister, and a woman must not ask to have her sister divorced in order to deprive her of what belongs to her, but she must marry, because she will have what Allah has decreed for her.
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.
Chapter 5: The prohibition of marriage for one who is in Ihram, and it is disliked for him to propose marriage
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).
Chapter 6: The prohibition of proposing marriage when one's brother has already proposed, unless he gives permission or gives up the idea
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.
