Hadiths 7.43 to 7.45

7.43:
Narrated Um Habiba: I said, "O Allah's Apostle! Marry my
sister, the daughter of Abu Sufyan." He said, "Do you like
that?" I said, "Yes, for even now I am not your only wife; and
the most beloved person to share the good with me is my
sister." The Prophet said, "But that is not lawful for me
(i.e., to be married to two sisters at a time.)" I said, "O
Allah's Apostle! By Allah, we have heard that you want to
marry Durra, the daughter of Abu Salama." He said, "You mean
the daughter of Um Salama?" I said, "Yes." He said, "By Allah
! Even if she were not my stepdaughter, she would not be
lawful for me to marry, for she is my foster niece, for
Thuwaiba has suckled me and Abu Salama; so you should neither
present your daughters, nor your sisters to me."

7.44:
Narrated Jabir:
Allah's Apostle forbade that a woman should be married to man
along with her paternal or maternal aunt.

7.45:
Narrated Abu Huraira: Allah's Apostle said, "A woman and her
paternal aunt should not be married to the same man; and
similarly, a woman and her maternal aunt should not be married
to the same man."
