Yahya related to me from Malik from Ismail ibn Abi Hakim that heheard Umar ibn Abd al-Aziz say, "One of the last things that theMessenger of Allah, may Allah bless him and grant him peace, said was,'May Allah fight the jews and the christians. They took the graves oftheir Prophets as places of prostration . Two deens shall not co-existin the land of the Arabs.' "
