Islamic hadith says Mohammed wanted Muslims to expel the Jews from the Arabian Peninsula

 From the Hadeeth Encyclopedia:

‘Umar ibn al-Khattāb (may Allah be pleased with him) reported that he heard the Messenger of Allah (may Allah’s peace and blessings be upon him) say: "I will certainly expel the Jews and the Christians from the Arabian Peninsula until only Muslims are left in it."  

This is considered an authentic hadith, and there are some variations. 

On the authority of Abu Ubaidah bin Al-Jarrah, may God be pleased with him, who said: The last thing the Prophet, may God bless him and grant him peace, spoke: “Expel the Jews of the people of Hijaz and the people of Najran from the Arabian Peninsula, and know that the worst of people are those who took the graves of their prophets as mosques.” 

This means that according to this hadith, also considered authentic, Mohammed's very last words were to ethnically cleanse Jews from Arabia.

To be sure, there are other interpretations - that Mohammed didn't mean the entire peninsula, or that he would have accepted dhimmi status for the Jews. But in Arabic it appears that this hadith is being taught straight, without limits. 

Even the Hadeeth encyclopedia's explanation is expansive rather than restrictive:

In this Hadīth, ‘Umar (may Allah be pleased with him) tells about the Prophet's determination to expel the Jews and Christians from the Arabian Peninsula so that there would not be two religions in the Peninsula and to keep it ever redolent of monotheism, with no trace of polytheism. That is because living near the disbelievers and socializing with them entail great evils, including the possibility of imitating them, admiring their beliefs, or assuming their mannerisms by the naive and gullible Muslims. Muslims must be distinguished and independent in their own homeland, and they should not mix with followers of the other religions. Hence, the Jews, Christians, Magi, and other disbelievers must be driven out of the Arabian Peninsula, which is exclusively for the Muslims. The Arabs are the first nation to receive the message of Muhammad (may Allah's peace and blessings be upon him) and their homeland is the place where revelation came down. Therefore, non-Muslims should never reside therein.  

It is hard to say that Islam isn't antisemitic when one of its most authentic traditions is that the last wish of their prophet was to ethnically cleanse Jews from the region.
