Wikipedia, as well as the rest of the Internet, assures me that Jesus is known as “عيسى ʿĪsā” in Arabic (not Issa). I don’t see any Google hits at all for “Ya’suua” so I don’t know what else He may be called.
You linked to “Jesus in Islam”, and Islam isn’t Arabic… but Islam.
There simply is no Jesus in Islam. There is only the moronic character of Issa (Isa, Ysa, etc… since as a previous poster said, transliteration is tricky) which has absolutely no bearing on the linguistic truth of Jesus’ name in various languages. Jesus’ name in Hebrew was Yehoshua, in Aramaic Yeshua, and in Latin, Jesus (Yay-soos). The true English equivalent is Joshua and the term Jesus used today in English is a result of the variance in the sound from the Latin-- as English does not employ a “Y” sound for the letter “J”, along with a lot more lenient observance of the way vowels are pronounced.
The actual Arabic rendering of the name Joshua itself is analogous to the Aramaic and is pronounced Yushua. Arabic-speaking Christians do NOT use Issa, but say Ya’suua-- which is much closer. Isa/Ysa/Issa is derived, in all likelihood, from Esau. There is simply no logical linguistic path to follow to render the name Issa/Ysa/Isa from the very concrete foundations of the semitic language group which includes Arabic, Hebrew and Aramaic. Issa is not Jesus merely translated into another language, nor is it an acceptable variant in the same.
Per the narrative and necessary interlacing of Mary we do read that Mary was pure and a virgin in Surah Three. We read that she was told by angels she would bear a son who would be called the Messiah. Aside from that, the narrative is from totally out of left-field. However, in Surah Four, verses One-Hundred Fifty-Seven and One-Hundred Fifty-Eight, we read that this concocted Issa was NOT crucified and Allah just made it appear so, and then Allah took this Issa fellow up to Heaven.
The mere use of similar names, or ascribing drastically different character profiles to names which are falsely-claimed as analogous to a rendering in another language, and completely changing the narrative, does NOT mean that person, name, or narrative claimed is the same or even good enough to pass Go. Certainly not when discussing the immutable and glorious truth of the Gospel. For example, I cannot take the C.S. Lewis character of the demon Screwtape, call him Nailgun, have him cast as a mere human that floats around writing blog posts to influence an election in peacetime, and then say this new story resembles The Screwtape Letters, Nailgun is Screwtape, or that the evil demon and the new character profile of the good guy are the same in effect. It might work for a Hollywood re-write, but it just doesn’t follow logic, reason, and truth-- of which Jesus Christ is the epitome.
There is no Jesus in Islam and even if there was, His name was never Isa prior to Muhammad making it up out of thin air!
Yasū‘ (يَسُوعَ)
Christian Arabic version of the name of Jesus (as opposed to the Islamic Arabic term Isa عيسى)
Yasū‘u l-Masīḥ (يَسُوعُ المسيح)
Jesus Christ
The “3” or “E” looking letter at the end (far left) of the first entry is an Ayn, and differs from Aleph as Aleph is always long. Allow me to translate each letter:
Ya’a (Y) with fatah (short “a” vowel sound)>Siin (S) with a dhamma (short “u” vowel sound), Waw (Long U, being in the middle of the word), Ayn (a variant of what in English would be an A sound, but very specific). Rendering: Ya’suua in a mix from the Aramaic and Arabic versions of Joshua. Conclusion: Only Islam erroneously has “Isa”(and its transliterated variants) as a name and this is even at odds with linguistic truth and parallel paths within the semitic language group. Its only possible source would be the name Esau along a path of linguistic bastardization. This isn’t surprising considering Muhammad had such mixed up narratives and character relations that he casts Mary as being under the care of Zechariah, etc.
Simply put, “Jesus” in Islam ain’t Jesus at all and neither is the name they use defensible in the Arabic language.
