There is no tradition of anti-Semitism in Islam
Holy books are what people make of them: after all, even the word of God needs to be understood and interpreted. The same applies to anti-Jewish statements in the Koran. Today, it isn't just so-called critics of Islam who describe them as anti-Semitic; Muslim hate-preachers too like to quote them. In the field of traditional Koranic exegesis, this is a new kind of misuse.
For over a thousand years, Muslims have worked hard to make their word of God applicable as a moral and legal doctrine. Scholars claimed the exclusive right to interpret it. While this process wasn't democratic, it guaranteed that extreme, isolated interpretations stood little chance.
Verses calling for violence against Jews, for example, are embedded in reports about historical events. When the Prophet emigrated from Mecca to Medina in 622, he formed an alliance with the local population, which included some Jewish tribes. It is said that when these tribes broke the contract, Mohammed and his followers took revenge. Hatred of Jews in the early Islamic tradition sprang from the precarious position of the Muslim community, which was in competition with social adversaries. When seen this way, it was clearly associated with a specific situation.
Islamic scholars have always seen it more or less like this. Over the centuries, Jewish life, culture, economy and scholarship thrived under Islamic rule. Historians are agreed that Jews had a much better life under Islam than under European Christianity. While there was, of course, violence against people of other faiths in the Islamic world too, Islamic scholars had more problems with Christians and the doctrine of the Holy Trinity, which to them smacked of polytheism.
No anti-Semitism founded on race or religion
The current debate in Germany about anti-Semitism among Muslim migrants must be viewed against this historical backdrop. There is no tradition of anti-Semitism in Islam founded either on race or religion. And yet these days, it is widespread in majority-Muslim countries.
Neither racism nor the violence that results from it can be justified. However, the acceptance of anti-Semitic prejudices among Muslims should be attributed to political and social rather than religious factors. Without the colonial subjugation of the Arab world in the nineteenth and twentieth centuries, the spread of anti-Semitic thought, both there and in other Islamic countries, is almost unthinkable.
