Yahya related to me from Malik from Ismail ibn Abi Hakim that he
heard Umar ibn Abd al-Aziz say, "One of the last things that the
Messenger of Allah, may Allah bless him and grant him peace, said was,
'May Allah fight the jews and the christians. They took the graves of
their Prophets as places of prostration . Two deens shall not co-exist
in the land of the Arabs.' "
Muwatta Malik Book 45, Hadith 17
