Yahya related to me from Malik from Abu'z-Zinad from al-Araj from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said "One cannot be married to a woman and her paternal aunt, or a woman and her maternal aunt at the same time."
Muwatta Malik Book 28, Hadith 21
← Previous Hadith Yahya related to me from Malik that he had heard that when asked whether it was permissible for a man to return to his wife if he had divorced her irrevocably and then another man had married her after him and died before consummating the marriage, al-Qasim ibn Muhammad said, "It is not halal for the first husband to return to her."

Malik said, about the muhallil, that he could not remain in the marriage until he undertook a new marriage. If he had intercourse with her in that marriage, she had her dowry.

Muwatta Malik Book 28, Hadith 20 Next Hadith → Yahya related to me from Malik from Yahya ibn Said that Said ibn al-Musayyab said, "It is forbidden to be married to a woman and her paternal or maternal aunt at the same time, and for a man to have intercourse with a female slave who is carrying another man's child."
