I can "prove" it by way of scripture. Like you quote Isaiah to "prove" that Jesus should have been called Immanuel by Mary but wasn't, i can cite the Quran:
Say: He, Allah, is One. Allah, the Eternal, the Absolute. Allah is He on Whom all depend. He begets not, nor is He begotten. And none is like Him.
Surat 112 (Sincerity)
Say: Our Allah and your Allah is One, and unto Him we surrender. Surat 29 (the Spider) verse 46.
