In December 2017, four imams -- at mosques in North Carolina, New Jersey and Texas -- called for killing Jews. Two of the imams quoted from a hadith that says:
"The last hour would not come unless the Muslims will fight against the Jews and the Muslims would kill them until the Jews would hide themselves behind a stone or a tree and a stone or a tree would say: Muslim, or the servant of Allah, there is a Jew behind me; come and kill him".
Two other imams, respectively, asked Allah "to destroy the Zionists and their allies, and those who assist them" and "to wreak vengeance upon the plundering oppressors".
Prior to these December calls, in July 2017, two imams in California (Riverside and Davis) also called for killing Jews. One imam quoted the hadith above. He later apologized, claiming that "The last thing that I would do is intentionally hurt anyone, Muslim, Jewish or otherwise. It is not in my heart".
