Right.....I stand corrected...the point I am trying to make is about "continuity in Identity"
No matter what language a Muslim speaks..we kept Allah subhanahu wa tala's and Mohammad (PBUH) name the same as it was revealed and given at birth.
So how difficult is it to pronounce esus?
Sindsagar, not sure if this is a digression, but there is ample historic evidence that Arab christians may have referred to Christ as 'Esaa (Ain-Yaa-Sin-Yaa). Foremost of these is circumstancial evidence that can be drawn from the writings of YuHanaa/YaHyaa bar Mansoor (John of Damascus), the chief administrator to the Umayyad king Obd-al-MLK.
In his book "Fount of Knowledge", he takes big strides at pointing out "frivilous tales" in the Quran, and even comments on the "Text of the Table" (Surah al-Maa'idah), yet somehow fails to point out that "MHMD" got the name of Christ wrong... This is an unforgivable mistake unless John (and other Arab christians) recognized the name of Christ as Esaa in Arabic.
Moreover, I seem to have read a research paper by Shibli Zaman, in which the writer pointed out that Yashu'a (Yodh-Alep--Shin-Ain-Vav: God Saved) seems like a later contraption by the Nestorian church from the Hebrew abbriviative Y-Sh-W (Ymach-Shemu-w-Zikru: May his name and memory be efaced), and the story of him being crucified and God in turn saved/ressurected/raised/took him.
The writer further points out that the name of Christ may have been Ya'ashu (Yodh-Alep--Ain-Shin-Vav: God-Made/Created) which in many ways refers back to him being thought of as the "Son of God"... it should further be pointed out that all pious people were referred to with such names and it was more of a symbolic title. It could have been that it later took on a literal/name form, just like all religions have done after their spiritual leaders.
