Volume 7, Book 62, Number 46:
Narrated Abu Huraira:
The Prophet forbade that a woman should be married to a man along with her paternal aunt or
with her maternal aunt (at the same time). Az-Zuhri (the sub-narrator) said: There is a similar order
for the paternal aunt of the father of one’s wife, for ‘Ursa told me that ‘Aisha said, “What is unlawful
because of blood relations, is also unlawful because of the corresponding foster suckling relations.”
