How can a Muslim leader face his devout Muslim subjects with a decision of friendship and peace with Jews when the mosques all over the Middle East recite Mohammed’s commandment to Muslims: “The Hour [Resurrection] will not take place until the Muslims fight the Jews, and kill them. And the Jews will hide behind the rock and tree, and the rock and tree will say: oh Muslim, oh servant of Allah, this is a Jew behind me, come and kill him!” (Sahih Muslim 41:6985, also Sahih Bukhari 4:52:177) This Hadith, issued by Mohammad making a whole group of people illegal to exist, was issued in the 7th century, not after the 1948 creation of the State of Israel. It is not a response to modern-day grievances; it is a permanent commandment.
