Muhammad's attitude towards Jews was basically neutral at the beginning. During his lifetime, Jews lived on the Arabian Peninsula, especially in and around Medina. They refused to accept Muhammad's teachings. Eventually he fought them, defeated them, and most of them were killed. The traditional biographies of Muhammad describe the expulsion of the Banu Qaynuqa in the post Badrperiod, after a marketplace quarrel broke out between the Muslims and the Jews in Medina and Muhammad's negotiations with the tribe failed.
