"I read a book to Ash-Sha'bi in which it was narrated from Jabir that the Prophet said: 'A woman should not be taken as a co-wife to her paternal aunt or her maternal aunt.' He said: 'I heard that from Jabir.'"
"I heard 'Aishah say: The Messenger of Allah said: 'What becomes unlawful (for marriage) through breast-feeding is that which becomes unlawful through birth.'"
"I said: 'O Messenger of Allah, why do you choose wives from among Quraish and not from among us?' He said: 'Do you have anyone in mind?' I said: 'Yes, the daughter of Hamzah.' The Messenger of Allah said: 'She is not permissible for me (to marry); she is the daughter of my brother through breast-feeding.'"
"Mention was made to the Messenger of Allah of the daughter of Hamzah (as a potential wife). He said: 'She is the daughter of my brother through breast-feeding.'" (One of the narrators) Shu'bah said: "Qatadah heard this from Jabir bin Zaid."
