It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) forbade marrying a woman and her paternal aunt together, or a woman and her niece together, or a woman and her maternal aunt together, or a woman and her niece together. And the Prophet (peace and blessings be upon him) also forbade marrying the younger over the elder, and the elder over the younger.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Do not marry a woman while her paternal aunt or maternal aunt is already present.

Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) has also narrated a similar type of Prophetic hadith.

It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) forbade certain matters, then he enumerated those matters, and among them was this: to combine a girl and her maternal aunt, and a girl and her paternal aunt, in one marriage. That is, this was among the matters from which the Prophet (peace and blessings be upon him) forbade.

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: One should not marry a woman and her paternal niece, nor a woman and her maternal niece, nor a paternal niece and her paternal aunt, nor a maternal niece and her maternal aunt.

It is narrated from Ibn Shihab that he was asked about a man who combines in his marriage a woman and her father's maternal aunt or her mother's maternal aunt, and combines a woman and her father's paternal aunt or her mother's paternal aunt. He replied: Qabeesah bin Dhu’ayb narrated that it is reported from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) forbade combining in one marriage a woman and her maternal aunt, and a woman and her paternal aunt. We think that a woman's mother's maternal aunt is in the same position as her own maternal aunt, and if there is such a relationship through breastfeeding, then the same ruling applies.

Narrated from Sayyidah Umm Salamah (may Allah be pleased with her) that Sayyidah Umm Habibah (may Allah be pleased with her) came and said: O Messenger of Allah! Do you have an interest in my sister? The Prophet (peace and blessings be upon him) said: What should I do with her? She said: Marry her. The Messenger of Allah (peace and blessings be upon him) said: Do you like that? She said: Yes, and after all, I am not the only one, and my sister is most deserving to share this goodness with me. The Prophet (peace and blessings be upon him) said: She is not lawful for me. She said: By Allah! I have come to know that you have sent a marriage proposal to Durrah bint Umm Salamah. The Messenger of Allah (peace and blessings be upon him) said: If she were lawful for me, even then I could not marry her, because the slave woman of Banu Hashim, Thuwaibah, nursed both me and her father. So do not present your sisters and daughters to me.

Narrated from Sayyiduna Bara’ bin Azib (may Allah be pleased with him), he says: I met my maternal uncle in such a state that he had a flag with him. I asked: Where are you going? He said: The Noble Prophet (peace and blessings be upon him) has sent me to a man who, after his father’s death, has married his (father’s) wife. The Prophet (peace and blessings be upon him) has sent me so that I may strike his neck, or kill him, and seize his wealth.

It is narrated from Sayyiduna Bara’ bin Azib (may Allah be pleased with him), he says: I met my maternal uncle, … then narrated the above-mentioned hadith, … however, at its end it is stated, Abu Abdur Rahman said: My father narrated this hadith only from Abu Maryam Abdul Ghafar, because there is a defect in it.

Narrated by Sayyiduna Bara’ bin Azib (may Allah be pleased with him), he says: During the blessed era of the Messenger of Allah (peace and blessings be upon him), my camels were lost, so I was going around different houses. Suddenly, I saw a caravan and horsemen; they advanced and circled in my courtyard. They demanded that a man be brought out. Then they neither asked him any question nor spoke to him, until they struck off his neck. When they left, I inquired about him. People informed me that he had married his father’s wife.
