Etymology of Persian آیا/âyâ “whether/if”

[PersoLatin]

What is the etymology of Persian آیا/âyä “whether, if” ?

Is it by any change related to the verb آمدن/âmadan?

 

[bearded]

آمدون/âmadan?

Sorry, I do not know any Persian/Farsi, but just out of curiosity I would like to ask: why the transliteration amadan, while (Arabic) letters show 'amaduun'? Is there a grammar or pronunciation reason? Thank you in advance.
