Volume 7, Book 63, Number 209:
Narrated Nafi’:
Whenever Ibn ‘Umar was asked about marrying a Christian lady or a Jewess, he would say: “Allah
has made it unlawful for the believers to marry ladies who ascribe partners in worship to Allah, and
I do not know of a greater thing, as regards to ascribing partners in worship, etc. to Allah, than that a
lady should say that Jesus is her Lord although he is just one of Allah’s slaves.”
