Can A Jew Say Kaddish for a Non-Jew?
What if the Non-Jew was an Enemy Terrorist That Wanted to Kill You?
Sefer Chassidim (Rabbi Yehuda haChassid, 12th century Germany) who said that one may pray for the soul of a gentile who saved Jews in times of persecution and crisis. Later authorities expanded this ruling for a ger (convert) to say kaddish for his non Jewish parents. Apparently there is no prohibition of saying kaddish for a non Jew, as the kaddish prayer is always acceptable, but the custom seems to have been limited.
Rav Ovadiah Yosef (Yechaveh Da'at Vol 6 Responsa 60) rules that a ger may say kaddish for his parents and brings a variety of sources. Noteworthy is that the Sefer Chassidim quotes the Yerushalmi (Megila Ch. 3 Par. 7) that one must bless Harbonah who gave suggestion to hang Haman. Yeshiva.co
Leftwing New York Jews Say Kaddish for Dead Hamas Terrorists JPress
Some comments to this tragic staging:
"Are these really Jews? If so. Do they understand what Kaddish means? If so have they attended a funeral in Israel for Jews killed in terrorist attacks? Do they have relatives who have been killed by terrorists? Do they have lone soldiers like I do in the IDF putting their life on the line to defend the Jewish State? Or is this as I suspect a twisted misguided intellectual exercise and they have no clue what a killul Hashem they are committing?"
"My zayde told me before he dies when I was only 12-years old that the worst anti-semites were the Jewish ones. I couldn't believe it because it was such a contradiction to me, but he said that I'll see it throughout my life...I have!"
"If over 72% of the Jewish electorate can vote twice for the most anti semitic President in US history, and then vote for Hillary Clinton who also is an anti-semite, what do you expect from these New York Left Wing Jews? We are better off with Christians as supporters of the State of Israel then these anti semitic Jews."
