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.
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).
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."
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).
