Namaste,

Here is a scholar's (whose learned analytic opinion is that both Xitian and Islamic scriptures are plagiarised versions of Judaism) take on their greetings:

Even the Muslim greeting Salam Alaikum is plagiarised from Shalom aleichem.

Shalom aleichem (/ʃəˌlɒm əˈleɪxəm, ˌʃoʊləm-/;[1][2] Hebrew: שָׁלוֹם עֲלֵיכֶם, šālōm ʿalēḵem;

Hebrew pronunciation: [ʃaˈloːm ʕaleːˈxem]) is a spoken greeting in Hebrew, meaning "peace be upon you". The appropriate response is aleichem shalom ("unto you peace")

(Hebrew: עֲלֵיכֶם שָׁלוֹם).[3][4] The plural form "עֲלֵיכֶם" is used even when addressing one person.

This form of greeting is traditional among Jews throughout the world.

The greeting is more common among Ashkenazi Jews.

Pranam.
