Ans.01. But the sounds of the W in English is ambiguous, thus the proper letter would be V, the rest of the letter of the word YHVH is acceptable.
02. I was not discussing that the slightly different pronunciation of the word god in Hebrew and Arabic is the proof that they are two different deity. So don't bring this argument with me. But if I have to express my opinion both of you can have the same word for god, but this doesn't mean you worship the same god, despite the efforts of Muhammad who tried to plagiarize the hebrew deity.
01. I think we are just going round and round in circles and there is no solution.
02. It is again wrong to say that our prophet "plagiarize" the jewish deity.
There were no jews or Christians in Makkah and more than two third of Quran was revealed during Makkah period, so your claim is just based on assumption and without any proof.
And similarity between Allah and YHWH is natural since they speak of the same deity and both originate from the same source.
There is no Plagirisation of any kind!!
